George Leo Haydock

They shall not teach, &c. So great shall be the light and grace of the new testament, that it shall not be necessary to inculcate to the faithful the belief and knowledge of the true God, for they shall all know him. (Challoner) — All shall know me, &c. This seems to signify that by the truths which Christ preached, and which the apostles published to all nations, the faithful in the new law should have a greater knowledge of God, of the true manner of worshipping him, and of heavenly things, and also greater and more abundant graces than they had before Christ’s coming. They shall also serve God with greater fidelity, by considering his mercy in sending them a Redeemer to free them from the slavery of sin and damnation, of which they stood guilty. (Witham)
