Q. 35. How is the covenant of grace administered under the New Testament?

Under the New Testament, when Christ the substance was exhibited, the same covenant of grace was and still is to be administered in the preaching of the Word,[133] and the administration of the sacraments of Baptism[134] and the Lord's Supper;[135] in which grace and salvation are held forth in more fulness, evidence, and efficacy, to all nations.[136]

Mark 16:15. And he said unto them, Go ye into all the world, and preach the gospel to every creature.

[134] Matthew 28:19-20. Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.

[135] 1 Corinthians 11:23-25. For I have received of the Lord that which also I delivered unto you, That the Lord Jesus the same night in which he was betrayed took bread: And when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me. After the same manner also he took the cup, when he had supped, saying, This cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me.
