Hebrews 5:12-14

Revised Standard Version Catholic Edition

¹² For though by this time you ought to be teachers, you need some one to teach you again the first principles of God’s word. You need milk, not solid food; ¹³ for every one who lives on milk is unskilled in the word of righteousness, for he is a child. ¹⁴ But solid food is for the mature, for those who have their faculties trained by practice to distinguish good from evil.
