I. Vocal prayer

From The Catechism of the Catholic Church

2700
Through his Word, God speaks to man. By words, mental or vocal, our prayer
takes flesh. Yet it is most important that the heart should be present to him
to whom we are speaking in prayer: “Whether or not our prayer is heard
depends not on the number of words, but on the fervor of our
souls.”²
