-They would have been taught both in hearing the gospel and in the established doctrinal instruction. The early church quickly established a system or school of instruction for new believers.
-Learning Christ is both a concept and conduct
-John 17:17; 2 Thessalonians 2:13
-NIV “came to know Christ” is literally in the Greek “they learned Christ” (emathete ton Christon)
-Here we can see both the:
a) proclamation (kerygma) of the gospel
b) teaching (didache) of the about Christ
-instruction at baptism (Col.3:8-12)
-4:22 does not begin a new sentence in the Greek so the “put off your old self” and “put on the new self” is directly connected in context to the ritual of baptism.
-The teaching of the revelation and Christian faith are directly (again) connected to morality and ethical living.

a) put off (apothesthai) – aorist infinitive (aorist means a once for all final action, infinitive indicates what they were taught) which means it is a single act based on time past. Put of Pagan ways. Colossians 3:9 has same expression. Putting off clothes is an image of changing identities.
b) put on – aorist infinitive, which means it is a single act based on time past

-This new life is in the image of God (Colossians 3:10)
-We have been renewed in the image of God, but it is necessary to continue to renew or minds
-“Ananeousthai” is present infinitive which indicates a continuing process. It is a fact that we are in the image of God through our new birth, but it is a developing process. This gives us a clue as to how to interpret 4:12-18.
