John 13:35 · Story · Love

See How They Love One Another

Tertullian reported the saying at Carthage, and the accounts of care for the sick come from Alexandria, Carthage and Caesarea in the third and fourth centuries.

When plague filled the streets of Carthage, its bishop told his church that caring for their own people only was nothing wonderful.

John 13:35 BSB
By this everyone will know that you are My disciples, if you love one another.”
Where
Carthage, Alexandria, Caesarea
When
197 to about 381 AD (probable)

Summary

On the night before He died, Jesus said that by their love for one another everyone will know that they are His disciples. Christian and pagan writers of the second to fourth centuries show how that sign looked to the people around the church, and the story keeps each account to what its writer records.

  • The saying that gives this story its name stands in chapter 39 of Tertullian's Apology, a defence of the Christians against the charges brought before the rulers of the empire.
  • Tertullian describes a voluntary monthly gift that fed and buried the poor and supported orphans, the aged, the shipwrecked and Christians held in the mines, on the islands and in prison.
  • Dionysius of Alexandria, in a letter Eusebius kept (Church History 7.22), describes Christians nursing their sick brethren and dying with them while pagans cast out their own sick.
  • Pontius, Cyprian's deacon, records that in the plague at Carthage the church's care went to all men and not only to the household of faith (Life of Cyprian 10).
  • Basil, bishop of Caesarea, built a house outside his city for the sick, and Gregory of Nazianzus says that Basil took the lead in tending them himself (Oration 43, section 63).

The Saying and the Deeds Behind It

Christian writers of the second to fourth centuries recorded the church's care for the poor and the sick.

See How They Love One Another is the story of a saying and of the deeds behind it. The deeds are a common fund for the needy, nursing in time of plague and a house for the sick, each told from the text that records it.

The story belongs to love, which Jesus named as the mark of His disciples, because it shows ordinary believers keeping His command in hard years. It answers a plain question: what did Christian love look like to the people who watched it, and how much of what is told about it can the sources bear? The page sets the accounts in order on a timeline, tells each from its own text, hears two pagan witnesses, and sets what the sources record apart from what modern writers have argued from them.

The Accounts in Order of Date

Six of the ten dates come from The Catholic Encyclopedia of 1908 to 1912.

Tertullian's Apology stands fifty-five years before the plague reached Carthage, and Gregory's oration on Basil nearly 130 years after it.

To scale: 8 of 10 stops dated; a ring is approximate; two dots joined are the two years held; a mark that would lie on another stands in a lane under the axis.

The Accounts From Three Cities

Five writers tell of the church's care at Carthage, Alexandria and Caesarea.

  1. Tertullian of Carthage197

    Tertullian addressed his Apology to the "Rulers of the Roman Empire" to answer the charges made against the Christians. In chapter 39 he describes how the church kept its treasure chest. Each member gave on the monthly day "if he likes", and "only if it be his pleasure, and only if he be able: for there is no compulsion; all is voluntary."

    The gifts were not spent on feasts. They went "to support and bury poor people, to supply the wants of boys and girls destitute of means and parents, and of old persons confined now to the house", to those who had suffered shipwreck, and to Christians held in the mines, on the islands or in prison "for nothing but their fidelity to the cause of God's Church".

    Then he reported what this care brought on the church (Apology 39).

    "But it is mainly the deeds of a love so noble that lead many to put a brand upon us. See, they say, how they love one another, for themselves are animated by mutual hatred; how they are ready even to die for one another, for they themselves will sooner put to death."

    The first words are the pagans' reproach, and the clauses after them are Tertullian's comment on the speakers.

  2. Dionysius of Alexandrialetter undated

    Dionysius, bishop of Alexandria, wrote a festal letter to his church as the feast drew near in a year of plague, and Eusebius kept it in his Church History 7.22.

    Of his own people Dionysius wrote, "The most of our brethren were unsparing in their exceeding love and brotherly kindness. They held fast to each other and visited the sick fearlessly, and ministered to them continually, serving them in Christ. And they died with them most joyfully" (7.22.7).

    Of the pagans he wrote, "They deserted those who began to be sick, and fled from their dearest friends. And they cast them out into the streets when they were half dead, and left the dead like refuse, unburied" (7.22.10).

    Read the page on Dionysius of Alexandria

  3. Cyprian and Pontius at Carthage252

    Plague reached Carthage in 252, and its bishop Cyprian wrote On the Mortality for his people.

    He asked what the plague was testing, "whether they who are in health tend the sick; whether relations affectionately love their kindred; whether masters pity their languishing servants; whether physicians do not forsake the beseeching patients" (section 16).

    His deacon Pontius records in his Life of Cyprian, which tells of Cyprian's death and so was written after it, that Cyprian gathered the people and taught "that there was nothing wonderful in our cherishing our own people only with the needed attentions of love". He said that a man would become perfect who did more than "the publican or the heathen" and "loved even his enemies", and he pointed to God, who gives sun and rain "not only to His people, but to aliens also" (Life of Cyprian 9).

    The church shared out the work according to each one's standing, and those too poor to give money gave their labour. Pontius sums up the result: "Thus what is good was done in the liberality of overflowing works to all men, not to those only who are of the household of faith" (Life of Cyprian 10). Banishment followed, as Pontius tells it, and Cyprian was put to death at Carthage in 258.

  4. Basil of Caesareaoration about 381

    In his oration on Basil, bishop of Caesarea, Gregory of Nazianzus described the house Basil had built for the sick: "Go forth a little way from the city, and behold the new city, the storehouse of piety, the common treasury of the wealthy". There, he wrote, "disease is regarded in a religious light, and disaster is thought a blessing, and sympathy is put to the test" (Oration 43, section 63). Tillemont, as the introduction to the oration in the Nicene and Post-Nicene Fathers reports, placed it soon after Gregory left Constantinople in June 381.

    At the new city the sick who had been "driven away from their cities and homes" were "no longer the objects of hatred, instead of pity on account of their disease". Gregory says that Basil "saluted them as brethren".

The Christians of Carthage called each other brethrenTertullian, Apology 39

Tertullian adds that the pagans were angry with the Christians for calling each other brethren, and he writes, "One in mind and soul, we do not hesitate to share our earthly goods with one another."

The nurses of Alexandria died with the sickDionysius, in Eusebius, Church History 7.22.2 to 9

Wailing filled the city "because of the multitude of the dead and dying" (7.22.2).

Many who nursed others took the sickness and died, among them presbyters, deacons and people of the highest reputation, and Dionysius judged that their death "seemed to lack nothing of martyrdom" (7.22.8). The survivors "took the bodies of the saints in their open hands and in their bosoms, and closed their eyes and their mouths", washed and clothed them, and soon received the same care themselves (7.22.9).

Cyprian described the disease of the plagueCyprian, On the Mortality 14

Cyprian described the constant flux, the continual vomiting, the eyes "on fire with the injected blood", and the feet and limbs that some lost to the disease.

Pontius described Carthage in the plaguePontius, Life of Cyprian 9

Pontius describes the city in the plague: "All were shuddering, fleeing, shunning the contagion, impiously exposing their own friends", and "No one did to another what he himself wished to experience" (Life of Cyprian 9).

Gregory answered the charge that Basil was proudGregory of Nazianzus, Oration 43, section 64

Gregory answered those who called Basil proud by asking whether "he who kissed the lepers" could treat the healthy with disdain (section 64).

Witnesses Outside the Church

Pagans blamed the Christians for disasters, and a pagan satirist and a pagan emperor each wrote of Christian care.

The Christians cared for the sick in cities that often blamed them for disaster. In chapter 40 of the Apology, the chapter after the saying, Tertullian reports another pagan cry: "if there is famine or pestilence, straightway the cry is, Away with the Christians to the lion!"

Lucian mocked the Christians' care for a prisonerLucian of Samosata, The Death of Peregrine

Lucian of Samosata, a pagan writer of satire, mocked the Christians in The Death of Peregrine for the care they gave a man in prison. "Orphans and ancient widows might be seen hanging about the prison from break of day", he wrote. He said of the Christians that "it was impressed on them by their original lawgiver that they are all brothers". The Fowler translation gives the satire no year.

Julian ordered hostels to match the Christians' careJulian, Letter 22, to Arsacius

In 362 the emperor Julian wrote to Arsacius, high priest of Galatia, and ordered hostels so "that strangers may profit by our benevolence". He called it disgraceful that the Galilaeans, his name for the Christians, supported the pagan poor as well as their own, so that "all men see that our people lack aid from us".

Who Wrote Each Account

Each account comes from a writer with his own standpoint, and the standpoint shows how much the account can bear.

Tertullian wrote to defend his churchTertullian, Apology 1 and 39

The saying reaches readers through Tertullian, a Christian writer defending his church before its accusers.

Dionysius writes of his own brethrenEusebius, Church History 7.22

Dionysius wrote to his own church, and the sick he names are "our brethren". His picture of the pagans who cast out their sick is a bishop's word to his own people.

Pontius writes of his own bishopPontius, Life of Cyprian 9 to 10

Pontius was Cyprian's deacon and wrote of his own bishop, so his praise is a disciple's. He says in plain words that the church's care in the plague went beyond its own members.

Gregory honours Basil, and Lucian and Julian write as opponentsOration 43; The Death of Peregrine; Letter 22

Gregory's account is an oration in Basil's honour. Lucian and Julian wrote as opponents of the church, and both still record its care.

What the Record Leaves Unsaid

Three gaps in the record bear on how far the accounts can be pressed.

Eusebius dates the letter of Dionysius by events, after a war in the city, and names no year. It can be placed only within his years as bishop, which The Catholic Encyclopedia gives as 247 or 248 to 264 or 265. The lines of the letter that Eusebius kept speak of nursing the brethren and leave unsaid whether the Christians of Alexandria nursed pagans as well.

None of the writers of this story records Christians nursing the sick in the plague of Marcus Aurelius's reign.

The Scriptures Behind the Accounts

Four passages of the New Testament teach the care these writers describe.

But I tell you, love your enemies and pray for those who persecute you, that you may be sons of your Father in heaven. He causes His sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. If you love those who love you, what reward will you get? Do not even tax collectors do the same? And if you greet only your brothers, what are you doing more than others? Do not even Gentiles do the same?
Matthew 5:44 to 47BSB

Cyprian's teaching in the plague, as Pontius reports it, follows these verses on loving enemies, the sun given to the evil and the good, and doing more than tax collectors and Gentiles.

Therefore, as we have opportunity, let us do good to everyone, and especially to the family of faith.
Galatians 6:10BSB

Paul tells believers to do good to everyone and especially to the family of faith, and Pontius keeps the same order when he says the care at Carthage reached all men.

By this we know what love is: Jesus laid down His life for us, and we ought to lay down our lives for our brothers.
1 John 3:16BSB

John ties knowing love to laying down life for the brothers, which is what Dionysius says the nurses of Alexandria did.

Continue in brotherly love. Do not neglect to show hospitality to strangers, for by so doing some people have entertained angels without knowing it. Remember those in prison as if you were bound with them, and those who are mistreated as if you were suffering with them.
Hebrews 13:1 to 3BSB

The letter joins brotherly love to hospitality to strangers and to remembering prisoners, the kinds of care Tertullian, Lucian and Julian describe.

1 John 3:16, Hebrews 13:1 to 3

Did Their Care Grow the Church?

Two scholars have argued that Christian care for the sick helped the church grow.

Care in the epidemics raised Christian survivalRodney Stark, The Rise of Christianity (1996)

Rodney Stark, a sociologist, gave the fourth chapter of The Rise of Christianity (Princeton University Press, 1996) to "Epidemics, Networks, and Conversion". The publisher's description of the book sets the argument amid the epidemics and other disasters of the cities of the empire. It says that "Christian communities were a stronghold of mutual aid, which resulted in a survival rate far greater than that of the pagans."

Health care as a reason for conversionHector Avalos, Health Care and the Rise of Christianity (1999)

Hector Avalos argued that "The ideas of health care reflected in early Christianity constitute a system that was an important factor in attracting converts". Felix Just, reviewing the book, judged that its main thesis, "no matter how intriguing or plausible, must unfortunately be regarded as unproven".

Every plague account in this story was written by a Christian, and none of them counts how many Christians and pagans survived.

By This Everyone Will Know

The saying names the mark Jesus gave His disciples.

Jesus gave His disciples love for one another as the sign by which everyone will know them. In Carthage and Alexandria that love was kept at the cost of life, and the church of Carthage was taught to give it to its enemies as well. The command itself, from John 13:34 to 35, is taught on the page Love One Another.
