1 Corinthians 12:5

We are all the one body of Christ, whose head is God, whose members we are. Some perhaps are the eyes, like the prophets. Others are more like teeth, as the apostles who passed the food of the gospel teaching into our hearts.… Some are hands who are seen carrying out good works. Those who bestow the strength of nourishment upon the poor are his belly. Some are his feet, and would that I were worthy to be his heel!

Just as a faculty of the human body will be idle when the causes that stir it into activity are not present, so with the soul. The eyes will not perform their functions except through the light or the brightness of day. The ears will not comprehend their task when no voice or sound is heard. The nostrils will not be aware of their office if no odor is detected. It is not that the faculty is lost because the cause is absent. Rather the employment of the faculty comes from the cause. It is the same with the soul of man. If the soul has not breathed in the gift of the Spirit through faith, even though it will continue to possess the faculty for understanding, it will not have the light of knowledge. The one gift, which is in Christ, is available to everyone in its entirety, and what is present in every place is given insofar as we desire to receive it and will remain with us insofar as we desire to become worthy of it. This gift is with us even to the consummation of the world. This is the consolation of our expectation. This, through the efficacy of the gifts, is the pledge of our future hope. This is the light of the mind, the splendor of the soul. For this reason we must pray for this Holy Spirit.

Let not, therefore, any one that works signs and wonders judge any one of the faithful who is not vouchsafed the same: for the gifts of God which are bestowed by Him through Christ are various; and one man receives one gift, and another another. For perhaps one has the word of wisdom, and another the word of knowledge; another, discerning of spirits; another, foreknowledge of things to come; another, the word of teaching; another, long-suffering; another, continence according to the law: for even Moses, the man of God, when he wrought signs in Egypt, did not exalt himself against his equals: and when he was called a god, he did not arrogantly despise his own prophet Aaron. Nor did Joshua the son of Nun, who was the leader of the people after him, though in the war with the Jebusites he had made the sun stand still over against Gibeon, and the moon over against the valley of Ajalon because the day was not long enough for their victory, insult over Phineas or Caleb. Nor did Samuel, who had done so many surprising things, disregard David the beloved of God: yet they were both prophets, and the one was high priest, and the other was king. And when there were only seven thousand holy men in Israel who had not bowed the knee to Baal, Elijah alone among them, and his disciple Elisha, were workers of miracles. Yet neither did Elijah despise Obadiah the steward, who feared God, but wrought no signs; nor did Elisha despise his own disciple when he trembled at the enemies. Moreover, neither did the wise Daniel who was twice delivered from the mouths of the lions, nor the three children who were delivered from the furnace of fire, despise the rest of their fellow-Israelites: for they knew that they had not escaped these terrible miseries by their own might; but by the power of God did they both work miracles, and were delivered from miseries. […]

"And there are diversities of ministrations, but the same Lord." Thus, enriching the consolation, he adds mention of the Son also, and of the Father. And again, he calls these gifts by another name, designing by this also an increase of consolation. Wherefore also he thus said: "there are diversities of ministrations, but the same Lord." For he that hears of "a gift," and hath received a less share, perhaps might grieve; but when we speak of "a ministration," the case is different. For the thing implies labor and sweat. "Why grievest thou then," saith he, "if he hath bidden another labor more, sparing thee?"

The Holy Spirit adapts himself to each person. He sees the dispositions of each. He sees into our reasoning and our conscience, what we say, what we think, what we believe.
