St. Thomas Aquinas was born of noble blood. He was expected to inherit the seat of Aquino, his home town, or at least to become the wealthy Benedictine abbot of Monte Casino. Aquinas, though, bumped into the Dominican Order early ;), and after that there was no turning back. He wanted to become a poor soldier for Christ, carrying the flame of His holy cross like a torch lit by a war band marching to the horizon; ever toward the dark hordes and shadow lands of Satan.
When the saint’s family heard about this, his two brothers went to fetch him. He evaded them and went to Rome, but they kidnapped him on the way. Imprisoning him in the family’s ancestral castle (yes, a real locked-tower prisoner), they ordered him to take off the habit and renounce his vows, since they wanted male heirs and he was the eldest son. He refused, and simply kept praying. Eventually, they sent in a prostitute to tempt him. Saint Thomas dismissed her, but she refused to leave. He then did what all normal and excellent saints would do: picked up a burning piece of wood from the fire and forced the temptress out! If that’s not manly virtue in devotion to chastity, I don’t know what is.
People often forget that chastity and temperance are the manly virtues. Since men are incredibly lust-filled and are more driven than women by urges to have sex (generally), it is a great struggle to be chaste. We are called to be good, quiet soldiers for Christ, not roaring lions who mount every female nearby. Thanks be to God!
