St. John Cantius supposedly often said:
“What kind of work can be more noble than to cultivate the minds of young people, guarding it carefully, so that the knowledge and love of God and His holy precepts go hand-in-hand with learning? To form young Christians and citizens-isn’t this the most beautiful and noble-minded way to make use of life, of all one’s talents and energy?
Two quotes from St. John Cantius which he had inscribed on the wall of his living quarters:
“Avoid slander because it is difficult to retract"—"Avoid offending anyone for to ask forgiveness is not delightful.”
St. John Cantius wrote that if a penitent is truly humbled and contrite, the confessor should;
“treat him compassionately out of consideration for the frailty of human nature.”
“…we look with reverence to the Church, in order that we might have life with the saints.”
St. John Cantius lived by the principle: Pauper venit, Christus venit. Once, when a pauper appeared while he was dining with friends, St. John Cantius exclaimed, “Christ has come” and invited him to the table.
