But, in the second and last place, hence also appears the error of the opinion, that seeing this exercise is performed in certain acknowledged duties, therefore by itself it is unnecessary. It is not denied that the oath is used to confirm civil obligations. But no one is therefore warranted in maintaining that to apply it so, is to use it in things religious. It is one thing to admit that vowing is a part of the duty implied in receiving the sacrament of baptism and the Lord's supper; it is another to maintain that the vow or oath should not be used in other circumstances. The vow is defined in Scripture, but the things to be vowed, and the cases in which it should be made are also in general pointed out. To declare that the vow should be made, for example, merely on sacramental occasions, would be to assume, that a part adopted by men should stand for the whole appointed by God. Is it said, that in these two sacramental exercises there is made a general engagement, that comprehends every duty that could possibly be performed, and therefore it is unnecessary to engage in formal Covenanting? On the same principle it might be said, that the sinner who has received Christ at first has no need to act faith upon him again;--that the believer has even no need to receive the ordinance of baptism for his children, or that of the Lord's supper for himself;--that the individual who has believed should not Covenant personally in an explicit manner; yea,--that he who has sworn to the Lord, in attending to the ordinance of baptism or of the supper, has no need in any case, even in reference to matters civil, to swear again. It might as well be said, that, in receiving the ordinance of baptism, vows are taken on, which include every case that could occur, and that, therefore, after that there is no necessity for waiting on the ordinance of the supper;--or that the waiting on that ordinance on one occasion would afford a reason for neglecting both the dispensation of it and of the ordinance of baptism ever thereafter. In one word, it might be answered, that the opinion makes no provision for the believer's growth in grace, but by dealing with him as if he were perfect in all respects, rather tends to keep him from attaining to perfection. One approved exercise is not to be sacrificed to others. On the same principle that Covenanting might be given up because vows are made to God in receiving the sacrament, might praise be given up because God is thanked in prayer; or prayer be discontinued because He is adored and thanked, and presented with confession of sin, and supplications for mercies, in songs of praise. But, besides, as the Lord's supper ought not to be substituted for baptism, nor baptism for the Lord's supper, so neither ought either or both to take the place of various other specific exercises of vowing to God. The vow made on the reception of baptism is suited especially to the occasion. Other vows
