ISB ~ 1 Corinthians 12 v13

by one Spirit:That is, by the divine action of the Spirit working in Baptism.

one body:This is not simply a metaphor for the Church, with the focus on her organizational unity, but it expresses the metaphysical reality that every believer is truly united with Christ by the Sacraments (10:17; CCC 790). The Spirit is the soul of this mystical body, giving life, growth, and direction to each of its members (CCC 797).

Jews or Greeks:Union with Christ makes ethnic and social distinctions irrelevant in the eyes of God (Gal 3:28; CCC 1267).

to drink of one Spirit:Baptism renews (Tit 3:5) and refreshes us through the Spirit (Jn 7:37-39), as does the spiritual drink of the Eucharist (1 Cor 10:4).
