Hebrews 5:12
For when for the time ye ought to be teachers, ye have need that one teach you again which be the first principles of the oracles of God; and are become such as have need of milk, and not of strong meat.

Prayer before a Crucifix
Behold, O Kind and most sweet Jesus, before Thy face I humbly kneel, and with the most fervent desire of soul, I pray and beseech Thee to impress upon my heart lively sentiments of faith, hope and charity, true contrition for my sins and a firm purpose of amendment. With deep affection and grief of soul, I ponder within myself, mentally contemplating Thy five wounds, having before my eyes the words which David the Prophet spoke concerning Thee: "They have pierced my hands and my feet, they have numbered all my bones."
