There are several places in the New Testament where the example of catechizing and the command to teach are emphasized. Apollos was “catechized” in the way of the Lord (Acts 18). Jesus commanded Peter in John 21:19 to feed his lambs. Teaching is obedience to the Holy Spirit’s command through Paul to Timothy, “These things command and teach” (1 Tim. 4:11)  (Donald Van Dyken, Rediscovering Catechism: The Art of Equipping Covenant Children, 12).
