Three sorts of prayer…

Prayer is of three sorts. The one is perpetual: it is holy perpetual desire, which prays in the sight of God…  for this desire directs all thy works, spiritual and corporal, to His honor, and therefore it is called perpetual…The other kind is vocal prayer, when the offices or other prayers are said aloud. This is ordained to reach the third – that is, mental prayer: your soul reaches this when it uses vocal prayer in prudence and humility, so that while the tongue speaks the heart is not far from God… And whenever one felt one’s mind to be visited by God, so that it was drawn to think of its Creator in any wise, it ought to abandon vocal prayer, and to fix its mind with the force of love upon that wherein it sees God visit it.
–Saint Catherine of Siena  (1347-1380)

Giving up prayer…

No soul ever fell away from God without giving up prayer. Prayer is that which establishes contact with Divine Power and opens the invisible resources of heaven. However dark the way, when we pray, temptation can never master us. The first step downward in the average soul is the giving up of the practice of prayer, the breaking of the circuit with divinity, and the proclamation of one’s owns self sufficiency.
–Blessed Fulton Sheen  (1895-1979)

Let us work for our salvation…

Let us work for the food which does not perish – our salvation. Let us work in the vineyard of the Lord to earn our daily wage in the wisdom which says: Those who work in me will not sin. Christ tells us: The field is the world. Let us work in it and dig up wisdom, its hidden treasure, a treasure we all look for and want to obtain. If you are looking for it, really look. Be converted and come. Converted from what? From your own willfulness.
–Saint Bernard of Clairvaux (1090-1153)
