1 John 2:9

Why do you rush into the darkness of jealousy? why do you enfold yourself in the cloud of malice? why do you quench all the light of peace and charity in the blindness of envy? why do you return to the devil, whom you had renounced? why do you stand like Cain? For that he who is jealous of his brother, and has him in hatred, is bound by the guilt of homicide, the Apostle John declares in his epistle, saying, "Whosoever hateth his brother is a murderer; and ye know that no murderer hath life abiding in him."24 And again: "He that saith he is in the light, and hateth his brother, is in darkness even until now, and walketh in darkness, and knoweth not whither he goeth, because that darkness hath blinded his eyes."25 Whosoever hates, says he, his brother, walketh in darkness, and knoweth not whither he goeth. For he goeth unconsciously to Gehenna, in ignorance and blindness; he is hurrying into punishment, departing, that is, from the light of Christ, who warns and says, "I am the light of the world. He that followeth me shall not walk in darkness, but shall have the light of life."26 But he follows Christ who stands in His precepts, who walks in the way of His teaching, who follows His footsteps and His ways, who imitates that which Christ both did and taught; in accordance with what Peter also exhorts and warns, saying, "Christ suffered for us, leaving you an example that ye should follow His steps."27

That charity and brotherly affection are to be religiously and stedfastly practised. In Malachi: "Hath not one God created us? Is there not one Father of us all? Why have ye certainly deserted every one his brother? " Of this same thing according to John: "Peace I leave with you, my peace I give unto you." Also in the same place: "This is my commandment, That ye love one another, even as I have loved you. Greater love than this has no man, than that one should lay down his life for his friends."

"He that saith he is in the light,"-in the light, he means in the truth,-"and hateth," he says, "his brother." By his brother, he means not only his neighbour, but also the Lord. For unbelievers hate Him and do not keep His commandments. Therefore also he infers: "He that loveth his brother abideth in the light; and there is none occasion of stumbling in him."

He begins speaking about love for one's neighbor. He says that closeness or love for God is recognized first of all from love for one's neighbor. For it is impossible that one illumined by the knowledge of God and filled with love for Him should …

How can someone say that he belongs to Christ and at the same time hate his brother for whom Christ died? Or if someone says he belongs to God and yet hates Christ, who has become our brother by becoming a man, he is not …

He who says he is in the light and hates his brother, etc. The Lord has commanded to love enemies; therefore, he who says he is a Christian and hates his brother is still in sins. And he rightly added "still," because all men undoubtedly …

He that saith he is in the light - In Christ, united to him. And hateth his brother - The very name shows the love due to him. Is in darkness until now - Void of Christ, and of all true light.

He that saith he is in the light,....

He who is governed by such love approves his light to be good and genuine: He that loveth his brother (as his brother in Christ) abideth in the light,

"Where love is not, there hatred is; for the heart cannot remain a void" [BENGEL]. in the light--as his proper element. his brother--his neighbor, and especially those of the Christian brotherhood. The very title "brother" is a reason why love should be exercised. even until now--notwithstanding that "the true light already has begun to shine" (1Jo 2:8).

He that saith he is in the light - He that professes to be a convert to Christianity, even in the lowest degree; and hateth his brother - not only does not love him, but wills and does him evil, as the Jews did the Gentiles; is in darkness - has received no saving knowledge of the truth; and, whatever he may pretend, is in heathen ignorance, or even worse than heathen ignorance, to the present time, notwithstanding the clear shining of the light of the Gospel.
