Roman Catechism 19.37

Chapter 19 — Part II: The Sacraments — Penance

Section 37. The sinner, then, who repents, casts himself humbly and sorrowfully at the feet of the priest, in order that by there humbling himself he may the more easily be led to see that he must tear up the roots of pride whence spring and flourish all the sins he now deplores. In the priest, who is his legitimate judge, he venerates the person and the power of Christ our Lord; for in the administration of the Sacrament of Penance, as in that of the other Sacraments, the priest holds the place of Christ. Next the penitent enumerates his sins, acknowledging, at the same time, that he deserves the greatest and severest chastisements; and finally, suppliantly asks pardon for his faults.
