Of the Sacraments

Sacraments ordained of Christ are not only badges or tokens of Christian men's profession, but rather they are certain signs of grace, and God's good will toward us, by which He works invisibly in us, and not only quickens but also strengthens and confirms our faith in Him. There are two sacraments ordained of Christ our Lord in the gospel — Baptism and the Supper of the Lord.

Go, and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,
— Matthew 28:19 (WEB)

Note

Two sacraments only — Baptism and the Lord's Supper. Both are "means of grace," not mere symbols.
