In this full and proper sense it is taken by Christ when he saith, Mark xvi. 16, "He that believeth and is baptized shall be saved;" that is, he that believeth, and is by baptism entered into the covenant of God; and in this sense the ancients took it, when they affirmed that all that were baptized were regenerated, pardoned, and made the children of God. And in this sense it is most true, that he that is baptized (that is, is a sincere covenanter) shall be saved if he die in that condition that he is then in.[40] All that the minister warrantably baptizeth, are sacramentally regenerate, and are _in foro ecclesiæ_ members of Christ, and children of God, and heirs of heaven: but it is only those that are sincerely delivered up in covenant to God in Christ, that are spiritually and really regenerate, and are such as shall be owned for members of Christ and children of God _in foro cœli_. Therefore it is not unfit that the minister call the baptized, regenerate and pardoned members of Christ, and children of God, and heirs of heaven, supposing that _in foro ecclesiæ_ they were the due subjects of baptism. But if the persons be such as ought not to be baptized, the sin then is not in calling baptized persons regenerate, but in baptizing those that ought not to have been baptized, and to whom the seal of the covenant was not due. None ought to be baptized but those that either personally deliver up themselves in covenant to God the Father, Son, and Holy Ghost, professing a true repentance, and faith, and consent to the covenant; or else are thus delivered up, and dedicated, and entered into covenant in their infancy, by those that, being christians themselves, have so much interest in them and power of them, that their act may be esteemed as the infants' act, and legally imputed to them as if themselves had done it. If any others are unduly baptized, they have hereby no title to the pardon of sin or life eternal, nor are they taken by God to be in covenant, as having no way consented to it.
