Claiming that paedocommunion isn’t found in Reformed history, as some of the well intended Reformed harpie police will shriek isn’t true. The Reformed tradition drew from Augustine, who advocated for paedocommunion as quoted below. In point of fact paedocommunion was non-controversial in his day. The great forerunner of the Reformation, Hus, was a paedocommunion advocate. As quoted below, during the Reformation, Wolfgang Musculus also advocated for paedocommunion and Luther, as we see below, was at least open.
Paedocommunion is not some strange modification of Reformed theology. It is consistent with Reformational baptismal theology and covenant theology.
“Those who say that infancy has nothing in it for Jesus to save, are denying that Christ is Jesus for all believing infants. Those, I repeat, who say that infancy has nothing in it for Jesus to save, are saying nothing else than that for believing infants, infants that is who have been baptized in Christ, Christ the Lord is not Jesus. After all, what is Jesus? Jesus means Savior. Jesus is the Savior. Those whom he doesn’t save, having nothing to save in them, well for them he isn’t Jesus. Well now, if you can tolerate the idea that Christ is not Jesus for some persons who have been baptized, then I’m not sure your faith can be recognized as according with the sound rule. Yes, they’re infants, but they are his members. They’re infants, but they receive his sacraments. They are infants, but they share in his table, in order to have life in themselves.”
St. Augustine, Sermon 174, 7
(1) Those who possess the thing signified also have a right to the sign
(2) Children who can receive the grace of regeneration (as is evident from Baptism) can also be nurtured in their spiritual lives without their knowledge.
(3) Christ is the Savior of the whole church, including the children, and feeds and refreshes all of its members.
(4) The demand for self-examination (I Cor. 11:26-29) is not intended by the apostle as a universal requirement.
Wolfgang Musculus — Loci Communes
Second Generation Reformer
Luther considered communing children to be not necessary but also not sin. He offered here;
“[They] pretend that children, not as yet having reason, ought not to receive [the sacrament]. I answer: That reason in no way contributes to faith. Nay, in that children are destitute of reason, they are all the more fit and proper recipients of [the sacrament]. For reason is the greatest enemy that faith has: it never comes to the aid of spiritual things, but – more frequently than not – struggles against the Divine Word, treating with contempt all that emanates from God.”
Martin Luther
Going behind the Reformation we find the Apostolic Constitutions written not by the Apostles circa 380 AD. The Apostolic Constitutions would have been written during the lifetime of St. Augustine. In this early church liturgy document we read that the children are included among the faithful that remain and take communion after the readings. Others who are not initiated (baptized) are excluded and excused from the communion. A door-wathcher keeps non-initiated out.
“As to the children that stand [the infant children do not stand, but are among the initiated who are prepared for communion], let their fathers and mothers take them to themselves …. After this, let all rise up with one consent, and, looking towards the east, after the catechumens and the penitents are gone out, pray to God eastward, …. Then let the sacrifice follow, all the people standing, and praying silently; and, when the oblation hath been made, let every rank by itself partake of the Lord’s body and precious blood, in order, and approach with reverence and holy fear, as to the body of their King. Let the women approach with their heads covered, as is becoming the order of women. Moreover, let the door be watched, lest there come in any unbeliever, or one not yet initiated. P 65
Let no one eat of them that is not initiated; but those only who have been baptized into the death of the Lord [all that are baptized, to include infants and children] p.145
[nowhere are baptized children excluded from any part of the Lord’s Day communion.]
Of course forbidding the covenant children from the sacrament of communion exists upon the same logic of forbidding the covenant children from the sacrament of Baptism. This forbidding amounts to a halfway covenant. Covenant children are seen as having one foot in the covenant and one foot outside the covenant. They are akin to the actual splitting in half of the legendary Solomonic baby and those Presbyterian and Reformed who refuse to commune their children, themselves have one foot in and one foot outside the circle of being logically consistent.
If I were a Baptist today and if I were debating a Presbyterian on the issue of covenant I would be forever banging the Presbyterians over the head regarding their wet but unfed covenant children.
This is just one reason why we insist that putative Presbyterians today are “wet baby Baptists.”
