Council of Trent: Session VII, On Baptism, Canon XIII

ON BAPTISM

CANON XIII.-If any one saith, that little children, for that they have not actual faith, are not, after having received baptism, to be reckoned amongst the faithful; and that, for this cause, they are to be rebaptized when they have attained to years of discretion; or, that it is better that the baptism of such be omitted, than that, while not believing by their own act, they should be bapized in the faith alone of the Church; let him be anathema.
