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;[1] the spiritual part of both is Christ and his benefits;[2] both are seals of the same covenant,[3] are to be dispensed by ministers of the gospel, and by none other;[4] and to be continued in the church of Christ until his second coming.[5]
