. . .It is very likely that Infants were Baptized with whole households. Is there any Scripture that forbids the Baptism of infants? Is there a Scripture that says one must reach an age of understanding, and if so what is that age and who determines this?
Infants were included in the Old Covenant, In fact, 8-day-old male infants were the ones who were circumcised, and their circumcision brought the women into Covenant with God.
Why would infants be excluded from the New Covenant, especially since the N.T. tells us Baptism is the Circumcision made without hands? This Circumcision made without hands is very important. Remember what the Lord said:
Isaiah 52 **
52 Awake, awake,
put on your strength, O Zion!
Put on your beautiful garments,
O Jerusalem, the holy city;
for the uncircumcised and the unclean
shall enter you no more.**
2 Shake yourself from the dust, rise up,
O captive Jerusalem;
loose the bonds from your neck,
O captive daughter Zion!
3**For thus says the Lord: You were sold for nothing, and you shall be redeemed without money. **
Ephesians 2:
11 Therefore remember that at one time you Gentiles in the flesh, called “the uncircumcision” by what is called the circumcision, which is made in the flesh by hands— 12 remember that you were at that time separated from Christ, alienated from the commonwealth of Israel and strangers to the covenants of promise, having no hope and without God in the world. 13 But now in Christ Jesus you who once were far off have been brought near by the blood of Christ. 14 For he himself is our peace, who has made us both one and has broken down in his flesh the dividing wall of hostility
Colossians 2:
8 See to it that no one takes you captive by philosophy and empty deceit, according to human tradition, according to the elemental spirits of the world, and not according to Christ. 9 For in him the whole fullness of deity dwells bodily, 10 and you have been filled in him, who is the head of all rule and authority.
11** In him also you were circumcised with a circumcision made without hands, by putting off the body of the flesh, by the circumcision of Christ, 12 having been buried with him in baptism, in which you were also raised with him through faith in the powerful working of God, who raised him from the dead.**
Wouldn’t this revelation of Baptism as a circumcision made without hands be the perfect place to say infants are excluded from the New Covenant, if that were the case? Yet, there is no such statement.
In fact, the New Covenant is more inclusive than the old.
Galatians 3 (ESV):
27 For as many of you as were baptized into Christ have put on Christ. 28 There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus. 29 And if you are Christ’s, then you are Abraham’s offspring, heirs according to promise. . . .
We do go back a bit, don’t we?
