Hebrews 5:12-14

Mace(i) 12 for though by this time you ought to be capable of teaching others, you want to be instructed anew in the first principles of the divine oracles; and are in such a state as to stand in need of milk, rather than of solid nourishment. 13 now he that is disciplined like a child, is not prepared for the doctrine of justification: 14 such solid nourishment is only fit for such as are arriv'd at their full growth and strength, whose senses have been exercis'd in distinguishing what is good, and what is prejudicial.
