[6.229.2] Since for now Your are for us only the true Son of the most Highest, as we know it from the mouth of the mother of Your body, how the archangel Gabriel appeared to her and has spoken to her: 'Be greeted who has found mercy before God! The holy spirit will overshadow you, and you will give birth to a boy, who you should call the son of the most Highest!'
[6.229.3] See, o Lord, this and still many things we know and cannot ward off the opinion, that there exist a most highest God-Father in heaven. You are His Son, and this unmistakenly, and a Third, most likely also God, equal to the Father and You, is apparently the Holy Spirit! - Are we wrong, if also we want to ascertain our faith?"
