For by one Spirit were we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.

For by one Spirit are we all baptized. He proves that Christ is one body with many members from baptism, for by baptism we were regenerate, and incorporated into the one body of the Church, and therefore into Christ. In that body we live by the same Spirit, the Spirit of Christ; and on the same food, the Eucharist, we are fed, whether we are Jews or Gentiles, bond or free. Notice the phrase "into one body:" this body is the Church, and consequently we are baptized into Christ, who, as I have said, is in a sense the body of the Church.
And have been all made to drink into one Spirit. In the Eucharistic chalice we have quaffed, together with Christ"s blood, His Spirit. Hence some Greek copies read, "We have all drunk of one draught." Cf. Clemens Alex. Pdag. lib. i. c6. The meaning is that from it we all partake of one and the same Spirit of Christ, who, by abiding in all, quickens every member, and makes it perform duly its function. In other words, not only were we born and incorporated into the said body, but we all partake of the same food, viz, Christ"s body and blood, in the Eucharist. For one species of the Eucharist leads easily to the other, and by "the drink" we may well understand "the food;" just as on the other hand from the species of bread we understand that of wine in chap. x17. Cf. Chrysostom and Cajetan, whose comments here are noteworthy.
It appears from this that all the baptized, whether good or bad, are the body of Christ, that Isaiah , are of the Church, and that they have been grafted into Him as members by baptism; for the soul of this body, the Church, is the faith which all the faithful have, even though their life be evil. Cf. notes to Ephesians 5:27.
