On the Catholic Priesthood
St. Paul, the Priest
In short, the reward of the priest’s labors will be in due proportion to the motives that urged his action. If he seeks “the things which are his own” his reward will be an earthly one. If he seeks “the things that are Christ’s” his reward will be an eternal one. Again, if his motive be a selfish one, the results of his labors in the care of souls will be negligible, because the grace of God can be but scantily with him, but working with the motive of the love of God great results may be expected, because the grace of God will amply accompany his efforts. For, with St. Paul, the priest who loves God sincerely may say: “I can do all things in him who strengtheneth me” (Phil., iv, 13). “For it is God who worketh in you (the faithful) both to will and to accomplish, according to his good will” (Phil., ii, 13).
