Concerning Paedocommunion: I've seen people argue that it is not "Reformed," that is, it is not in line with the historic, Reformed confessions. This point I will grant, though there certainly were some Reformers who held it. This also assumes a mythological idea of a monolithic "Reformed Church" or "Reformed view" on any given matter, but we won't go down that road. I've seen people argue against it exegetically, arguments being mainly drawn from 1 Corinthians 11. I ardently disagree with their interpretations of that passage. In fact, I think 1 Corinthians is one of the strongest defenses of Paedocommunion. Regardless, I can understand their line of argumentation. What I have not seen is an explanation of how Paedocommunion is anything but a valid practice of the historic catholic Church. The Eastern Orthodox Church has literally practiced it forever. We have multiple explicit statements from the early Church that support Paedocommunio
