“Until I come, devote yourself to the public reading of Scripture, to preaching and to teaching.
Do not neglect your gift, which was
given you through prophecy when the
body of elders laid their hands on you. Be diligent in these matters; give yourself wholly to them, so that everyone may see your progress.”
1 Timothy 4:13-15 NIV
These were considered elementary teachings - taken as assumed normative average Christian life. To my understanding-
“Therefore let us move beyond the elementary teachings about Christ and be taken forward to maturity, not laying again the foundation of repentance from acts that lead to death, and of faith in God, instruction about cleansing rites, the
laying on of hands, the resurrection of the dead, and eternal judgment. And God permitting, we will do so.”
Hebrews 6:1-3 NIV
