Since, then, the Same wrought in Paul Who wrought in Peter, it is certainly evident that, since the Spirit wrought in Paul, the Holy Spirit wrought also in Peter. But Peter himself testifies that God the Father wrought in him, as it is stated in the Acts of the Apostles that Peter rose up and said to them: “Men and brethren, ye know that a good while ago God made choice amongst us that the Gentiles should hear the word of the Gospel from my mouth.” See, then, in Peter God wrought the grace of preaching.
