Westminster Confession of Faith
Chapter 7: Of God’s Covenant with Man
6: Under the Gospel, when Christ, the substance,[155] 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:[156] which, though fewer in number, and administered with more simplicity, and less outward glory, yet, in them, it is held forth in more fullness, evidence, and spiritual efficacy,[157] to all nations, both Jews and Gentiles;[158] and is called the New Testament.[159] There are not therefore two covenants of grace, differing in substance, but one and the same, under various dispensations.[160]
