John Calvin Commentary 1 Corinthians 12:11

"but all these worketh the one and the same Spirit, dividing to each one severally even as he will." — 1 Corinthians 12:11 (ASV)

One and the same spirit distributing. From this, it follows that those act wrongly who, having no concern about participation, break apart that holy harmony, which is properly adjusted in all its parts only when, under the guidance of the same Spirit, all work together toward one and the same goal.

He again calls the Corinthians to unity by reminding them that all have received whatever they possess from one source. At the same time, he instructs them that no one has so much as to be self-sufficient, so as not to require help from others.

For this is what he means by these words: distributing to every one severally as he willeth. The Spirit of God, therefore, distributes them among us so that we may bring all to contribute to the common good. He gives all gifts to no single person, so that no one, satisfied with his particular portion, might separate himself from others and live solely for himself.

The same idea is intended in the adverb severally, as it is very important to understand accurately that diversity by which God unites us to one another. Now, when will is attributed to the Spirit, and that in connection with power, we may conclude from this that the Spirit is truly and properly God.
