Q176. Wherein do the sacraments of baptism and the Lord's supper agree?

The sacraments of baptism and the Lord's supper agree, in that the author of both is God; the spiritual part of both is Christ and his benefits; both are seals of the same covenant, are to be dispensed by ministers of the gospel, and by none other; and to be continued in the church of Christ until his second coming.
