“In the life of the body a man is sometimes sick, and unless he takes medicine, he will die: even so in the spiritual life a man is sick on account of sin; wherefore he needs medicine so that he may be restored to health; and this grace is bestowed in the Sacrament of Penance: Who forgiveth all thy iniquities, Who healeth all thy diseases.” (St. Thomas Aquinas, Doctor of the Church)
January 28 is the Memorial of St. Thomas Aquinas, Priest and Doctor of the Church (1225 – 1274).
