1. Prayer is an act of the virtue of religion. But only God is to be worshipped by the virtue of religion. Consequently it is to Him alone that we should pray. But in our prayers we only show religious worship to Him from Whom we hope to obtain what we ask, for by so doing we confess Him to be the Author of all our goods; but we do not show religious worship to those whom we seek to have as intercessors with us before God. 2. Again, prayer to those who cannot know what we pray for is idle. But God alone can know our prayers, and this because prayer is frequently a purely interior act of which God alone is cognizant, as the Apostle says: _I will pray with the spirit. I will pray also with the understanding_;[124] and also because, as S. Augustine says[125]: The dead know not, not even the Saints, what the living--not even excepting their own children--are doing. It is true that the dead, if we consider only their natural condition, do not know what is done on earth, and especially do they not know the interior movements of the heart. But to the Blessed, as S. Gregory says,[126] manifestation is made in the Divine Word of those things which it is fitting that they should know as taking place in our regard, even the interior movements of the heart. And, indeed, it is most befitting their state of excellence that they should be cognizant of petitions addressed to them, whether vocally or mentally. Hence through God's revelation they are cognizant of the petitions which we address them. 3. Lastly, some say: if we do address prayers to any of the Saints, the sole reason for doing so lies in the fact that they are closely united to God. But we do not address prayers to people who, while still living in this world, are closely knit to God, nor to those who are in Purgatory and are united to Him. There seems, then, to be no reason why we should address prayers to the Saints in Paradise. But they who are still in the world or in Purgatory do not as yet enjoy the vision of the Divine Word so as to be able to know what we think or say, hence we do not implore their help when we pray; though when talking with living people we do ask them to help us. * * * * *
