ACC ~ 1 Corinthians 14 v15
PRAY WITH THE SPIRIT AND THE MIND. ORIGEN: For our mind would not even be able to pray unless the Spirit prayed for it as if obeying it, so that we cannot even sing and hymn the Father in Christ with proper rhythm, melody, measure and harmony unless the Spirit who searches everything, even the depths of God, first praises and hymns him whose depths he has searched out and has understood as far as he is able. ON PRAYER 4.
PRAY WITH THE SPIRIT. GREGORY OF NAZIANZUS: Worshiping and praying in the Spirit seem to me to be simply the Spirit presenting prayer and worship to himself. THEOLOGICAL ORATION 31.12.
PRAYER BEYOND PSALMODY. ABRAHAM OF NATHPAR: It is in spirit and mind that one should pray and sing to God. Paul does not say anything about the tongue. The reason is that this spiritual prayer is not offered up or prayed by the tongue, for it is deeper than the lips and the tongue, more interiorized than any composite sounds, lying beyond psalmody and wisdom. ON PRAYER 2.
SING WITH THE SPIRIT. CASSIODORUS: The prayer of those who sing is acceptable to God only if a pure heart carries the same message which the words of the hymn unfold. EXPLANATION OF THE PSALMS 2.
