Chapter 33 — Part IV: Prayer — On Prayer in General
Section 64. In the performance of this duty, it is strictly incumbent on all not to transfer to any creature the right which belongs exclusively to God. For instance, when we say the Our Father before the image of a Saint we should bear in mind that we beg of the Saint to pray with us and to obtain for us those favours which we ask of God, in the Petitions of the Lord's Prayer, -- in a word, that he become our interpreter and intercessor with God. That this is an office which the Saints discharge, St. John the Apostle teaches in the Apocalypse.
