Luther

“When they say, 'children cannot believe,' how can they be sure of that? Where is the Scripture by which they would prove it and on which they would build? They imagine this, I suppose, because children do not speak or have understanding. But such a fancy is deceptive, yea, altogether false, and we cannot build on what we imagine.” Martin Luther, Concerning Rebaptism, LW, AE, 40:241-242
