This was practically acknowledged by believers in the apostolic age. The common fund that was raised from the contributions of the Church assembled and addressed by Peter on the day of Pentecost, was devoted by solemn vows. From what was said by that Apostle to Ananias and Sapphira his wife, this appears. "Ananias, why hath Satan filled thine heart to lie to the Holy Ghost, and to keep back part of the price of the land? While it remained, was it not thine own? and after it was sold, was it not in thine own power? Why hast thou conceived this thing in thine heart? thou hast not lied unto men, but unto God." "How is it that ye have agreed together to tempt the Spirit of the Lord?"[428] If a promise or vow to God to give up their substance had not been made, the language of reproof addressed to them would have been inapplicable. It is true, that when one lies to men, he disobeys God. But the language, "thou hast not lied unto men, but unto God," must intimate that the possession of the two individuals had been, either publicly before their brethren, or secretly, or in both ways, vowed to God. The conclusion is corroborated by the obvious consideration, that the practice of acting in this manner, although not to such an extent, was quite in accordance with that of vowing things to God under the dispensation that had then been brought to a close; and especially by the very language of Peter, "Whilst it remained, was it not thine own? and after it was sold, was it not in thine own power?" precisely agreeing with the words of the Old Testament record, "But if thou shalt forbear to vow, it shall be no sin in thee." Again, the practices of making confession, and of professing, which we have found to be in reality the making of Covenant engagements, would appear from the references made to them by the inspired writers, to have been ordinary occurrences of their times. And, lastly, the conduct of the Macedonian Churches, in giving themselves to the Lord, to which we have had occasion to refer, is worthy of being remembered as an authenticated source of Covenanting in those times, that had been performed by many, in one of the spheres where the truth had most manifestly taken effect.
The practice was provided for through the direct injunctions of the last inspired writers. These, dissuading from idolatry,[429] taught the necessity of the practice, the reverse of that, of recognising God and acknowledging him by vowing and swearing to him as a covenant God. Teaching the necessity of faith and other graces, they showed that it is dutiful to engage in that and those other exercises in which these are requisite. They explicitly enjoin the exercise of Covenanting.[430] Inculcating the holding fast of the Christian profession,[431] an apostle teaches that such a profession should not merely be adhered to, but also made. And delivering the express words of the Redeemer, the last of the apostles, teaching the duty of entering into covenant engagements, and keeping them till Christ should come, tendered the command, "But that which ye have already, hold fast till I come."[432]
The practice was provided for through the whole of the New Testament writings.
The New Testament contains the same kinds of expression in reference to the Covenant of God as the Old, and employs them for the same purpose as that for which those statements of that Testament are used. It makes use of figurative and other language of the same origin as that of the Old Testament, for the purpose of inculcating nothing else than the keeping of the Covenant.
By an apostle, there is strikingly brought into view the truth taught in the prophets,—that the Lord created, or formed, or fore-ordained, a people, to enter into Covenant with him, and by obedience also, otherwise to keep it.[433]
The imagery of the foundation[434] employed in prophecy to point out Christ, and the sureness and continuance of the Covenant, is also used by two apostles for the same purpose. Their references to it illustrate the doctrine, that, in the New Testament, types, though realized in Christ, and also partly illustrated in the blessings at any time bestowed by Him, are not to be disregarded but studied, that the good things prefigured by them, but as yet unattained, may be enjoyed.
The designation of the Holy Spirit, as the "Spirit of promise,"[435] teaches that He was given in consequence of the arrangements of the Covenant of God; and consequently, that all the benefits bestowed on believers, not merely in Old but also in New Testament times, were to come to them in connection with the acceptance of the gift of the Spirit, as included in the promise of the Covenant.
The idea of reconciliation, dwelt on by the apostles, necessarily implies the notion of a covenant agreement, as being not merely made but maintained, between God and men—once exposed to his curse, but afterwards put in possession of an interest in the atonement of Christ.
References made by the apostles to purification cannot be explained independently of the principle of, a covenant ratified by the blood of Christ being the channel of the communication of faith and the other graces, and of sanctification—that results from the implantation, support, and direction of these by the Holy Ghost.
The sprinkling, whether of blood or of water, referring to the operation of the Spirit, is introduced by an apostle as enjoyed by those who take hold on God's covenant.[436]
