St. Gregory the Theologian on Holy Baptism

“Do you have an infant child? Allow sin no opportunity; rather, let the infant be sanctified from childhood. From his most tender age let him be consecrated by the Spirit. Do you fear the seal [of baptism] because of the weakness of nature? Oh, what a pusillanimous mother and of how little faith!” St. Gregory the Theologian – Oration on Holy Baptism 40:7 [A.D. 388]
