ACC ~ 1 Peter 1 v2b

THE SPIRIT KNOWS ETERNALLY. ORIGEN: We must not suppose that the Spirit knows God as we do, only through the historic revelation of the Son. For if the Holy Spirit knows God only in this way, then he has passed from ignorance to knowledge, and it is certainly as impious as it is foolish to confess him as the Holy Spirit and then ascribe a prior ignorance to him. ON FIRST PRINCIPLES 1.3.4.

FATHER, SON AND SPIRIT. ANDREAS: See how Peter says that he was called to be an apostle of Jesus Christ by the foreknowledge of God the Father. Furthermore, he explains what his apostleship is like by saying that it is in the sanctification of the Spirit, for obedience and sprinkling with the blood of Jesus Christ. Moreover, we who believe in him have also been sanctified by the Spirit, and he sprinkles us too with his blood in order to cleanse us. For how can we not know that God sanctifies us by his own Spirit and cleanses us believers with his own blood? For Christ was God in human flesh. CATENA.

FOR OBEDIENCE TO JESUS CHRIST. BEDE: They were chosen for the purpose of being sanctified by the Holy Spirit so that once they had been cleansed from all their sins, those who had perished by their disobedience might start to obey the Lord Jesus Christ and, by being sprinkled with his blood, escape the power of Satan.
