There are several things mentioned in this answer, of which, it is said, to be a sign and seal, viz. of our engrafting into Christ, and obtaining remission of sins by his blood, of our regeneration by his Spirit, our adoption, and resurrection unto eternal life, which include in them all the benefits of Christ’s mediation; which have been particularly explained under some foregoing answers: But there is one that contains in it all the rest; and accordingly it is generally expressed, by divines, as that which is a sign and seal of the covenant of grace, and all the duties, obligations, and privileges that are either enjoined or bestowed therein. What this covenant is, together with the blessings thereof, and how the grace of God is manifested therein, has been likewise considered under some foregoing answers[[65]]. Therefore all that I shall now add concerning it, is, that it contains all the promises in which our salvation is included, of which there is one that comprehends all the rest, whereby it is often expressed, namely, that God will be a God unto his people, Gen. xiv. 1. their shield, and exceeding great reward, chap. xvii. And elsewhere that he will put his laws into their minds, and write them in their hearts, and will be to them a God; and they shall be to him a people, Heb. viii. 10. There are very great privileges contained in this relation, namely, our being under the special care and protection of Christ, having a right to what he has purchased, and that inheritance which he has laid up in heaven for his children, their enjoying communion with him here, and being made happy with him hereafter.
Now the main thing to be considered, is, how baptism is a sign and seal thereof? To this it may be answered, that we are not to suppose that this, or any other ordinance, confers the grace of the covenant, as the Papists pretend[[66]]; for it is, at most, but a significant sign or seal thereof; whereas, the grace of the covenant is the thing signified thereby. There are, as has been before observed two ways, by which persons may be said to be in covenant with God, namely, professedly, or visibly, which is the immediate intent and design of this ordinance; and there is a being in covenant, as laying hold on the grace of the covenant, when we give up ourselves to Christ, by faith; and, as the consequence thereof, lay claim to the blessings of his redemption. Now baptism is a sign and seal of the covenant of grace in both these senses, though in different respects. The ordinance itself is a professed dedication to God, or an acknowledgment that the person baptized is obliged to be the Lord’s; and signifies his right to the external blessings of the covenant of grace, which are contained in the gospel-dispensation. There is also more than this contained in a person’s being given to God in baptism, whether it be by himself as in those who are baptized when adult; or by his parents, as in the case of infants, in that the person who dedicates, expresses his faith in Christ, the Mediator of the covenant, and hopes for the saving blessings which he has purchased for his people. It is one thing, for this ordinance to confer these blessings, and another, for it to be an instituted means, in which we express our faith and hope, that these blessings shall be bestowed, the person being devoted to God with that view.
There are other two things that are more especially signified in baptism, namely, privileges expected, and obligations acknowledged.
1. The privileges expected are such as accompany salvation, which are the special gift of the Holy Ghost, viz. the taking away the guilt and pollution of sin, and our being made partakers of all the blessings that Christ hath purchased, and God the Father, in him, has promised to the heirs of salvation. I do not say, that all who are baptized are made partakers of these privileges; but they are given up to God, or give up themselves to him in this ordinance, in hope of obtaining them.
2. Here is a public profession, or acknowledgment of our obligation to be the Lord’s. This is, from the nature of the thing, implied in its being a dedication to God. When we make a surrender of ourselves to him, we do hereby declare, that we are willing to be his servants and subjects, and entirely at his disposal: This is contained in a fiducial act of self-dedication to God, and cannot be done by one in the behalf of another: And, it is to be feared, that many, who give up themselves to God in this ordinance, when adult, though they make a profession of their faith, yet do not give up themselves by faith; but that is only known to the heart-searching God: Nevertheless, as we express our faith and hope, in this ordinance, concerning the privileges but now mentioned; so we, in this act of dedication, confess, that God has a right to us, and that it is our indispensible duty to be his, so that hereby we are, either by our own consent, as in self-dedication, professedly the Lord’s; or this is acknowledged by those who have a right to dedicate, and thereby to signify this obligation; which, because it is highly just and reasonable, the persons devoted are obliged to stand to, or else are brought under a great degree of guilt, in not being stedfast in God’s covenant.
There is one thing more mentioned in this answer, namely, that the person baptized, is solemnly admitted into the visible church, which I rather choose to pass over; since it is hard to understand what some mean by the visible church, and a person’s becoming a member thereof by baptism. We have elsewhere considered the difficulties that are contained in the description of the visible church; together with the qualifications for, and admission of persons into church-communion.[[67]] If, by being admitted into the visible church, we are to understand that a person has a right to all the ordinances of the church by baptism, without being admitted afterwards into it by mutual consent; this is contrary to the faith and practice of most of the reformed churches. And if, on the other hand, they mean hereby, that here is a public declaration of our hope, that the person baptized shall be made partaker of those privileges which Christ has purchased for, and given to his church: This is no more than what has been already explained in our considering the baptismal expectations and obligations; but, whether this can be properly called an admission into the church, I rather leave to be determined by those who better understand what they mean, when they say that this is done in baptism, than I do.[[68]]
Quest. CLXVI.
Quest. CLXVI. Unto whom is baptism to be administered?
Answ. Baptism is not to be administered to any that are out of the visible church, and so strangers from the covenant of promise, till they profess their faith in Christ, and obedience to him; but infants descending from parents, either both, or but one of them, professing faith in Christ, and obedience to him, are in that respect within the covenant, and to be baptised.
In this answer, which principally respects the subjects of baptism, we have,
