It is objected that paedobaptists are strangely inconsistent in dispensing baptism to infants and yet refusing to admit them to the Lord’s Table …
At the outset it should be admitted that if paedobaptists are inconsistent in this discrimination, then the relinquishment of infant baptism is not the only way of resolving the inconsistency. It could be resolved by going in the other direction, namely, that of admitting infants to the Lord’s Supper.
And when all factors entering into this dispute are taken into account, particularly the principle involved in infant baptism, then far less would be at stake in admitting infants to the Lord’s Supper than would be at stake in abandoning infant baptism.
This will serve to point up the significance of infant baptism in the divine economy of grace.
