Christian education in the congregation is a ministry of the church we receive from Jesus in his final words to the disciples.  

18 And Jesus came and said to them, “All authority in heaven and on earth has been given to me. 19 Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 teaching them to observe all that I have commanded you; and lo, I am with you always, to the close of the age.” -Matthew 28:18-20 (RSV)
