I was thinking about the practice of paedobaptism and communion as practiced in reformed Presbyterian churches. A major distinction in this camp is Covenant Theology which sees one covenant (that of grace) in both the OT and NT.
One of the reasons they practice paedobaptism is because it is a NT version of circumcision (Col 2:11-12).
Then i got to thinking that Communion is a NT version of Passover as is obvious from the Passover meal in which Christ initiated it. Wasn’t OT Passover shared with the children?
At first i felt that there was hypocrisy in this line of thinking – paedobaptism and anti-paedocommunion. But then i realized that it is the NT itself that changes the ordinance of Commuion by telling us not to take it in an unworthy manner, and that we must examine ourselves (1 Cor 11:27-28).
Baptism is a passive sacrament, it is administered to somebody. Communion is an active sacrament, we are to take it, eat/drink it, examine ourselves.
So after considering the NT admonishment of how we are to actively participate in communion, i am fully behind paedo-baptism and non-paedo-communion.
