Context

“since, where there is one nature, there must needs be one power and one operation: whence our Lord says (John 5:19) : "What things soever the Father doth, these the Son also doth in like manner." Therefore it belongs to the whole Trinity to adopt men as sons of God. Reply Obj. 1: All human individuals are not of one individual nature, so that there need be one operation and one effect of them all, as is the case in God. Consequently in this respect no comparison is possible. Reply Obj. 2: By adoption we are made the brethren of Christ, as having with Him the same Father: Who, nevertheless, is His Father in one way, and ours in another.” source
