Paragraph 7.3
Of the Second London Baptist Confession of Faith
This covenant is revealed in the gospel; first of all to Adam in the promise of salvation by the seed of the woman,1 and afterwards by farther steps, until the full discovery thereof was completed in the New Testament;2 and it is founded in that eternal covenant transaction that was between the Father and the Son about the redemption of the elect;3 and it is alone by the grace of this covenant that all the posterity of fallen Adam that ever were saved did obtain life and blessed immortality, man being now utterly incapable of acceptance with God upon those terms on which Adam stood in his state of innocency.4
The Westminster Confession of Faith (1646)
7.5
This covenant was differently administered in the time of the law and in the time of the gospel:1 under the law it was administered by promises, prophecies, sacrifices, circumcision, the paschal lamb, and other types and ordinances delivered to the people of the Jews, all fore-signifying Christ to come,2 which were for that time sufficient and efficacious, through the operation of the Spirit, to instruct and build up the elect in faith in the promised Messiah,3 by whom they had full remission of sins and eternal salvation; and is called the Old Testament.4
7.6
Under the gospel, when Christ the substance1 was exhibited, the ordinances in which this covenant is dispensed are the preaching of the Word and the administration of the sacraments of Baptism and the Lord's Supper;2 which, though fewer in number, and administered with more simplicity and less outward glory, yet in them it is held forth in more fulness, evidence, and spiritual efficacy,3 to all nations, both Jews and Gentiles;4 and is called the New Testament.5 There are not, therefore, two covenants of grace differing in substance, but one and the same under various dispensations.6
