Puritan Board Freshman
VI. Under the Gospel, when Christ, the substance, 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: 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, to all nations, both Jews and Gentiles; and is called the New Testament. There are not therefore two covenants of grace, differing in substance, but one and the same, under various dispensations
Two questions:
1. What exactly does the confession mean when it refers to Christ as "the substance"?
2. How we are to understand the fact that under the Gospel the administration of the covenant of grace has more "spiritual efficacy"?
