488. How is Holy Baptism with water dispensed?

Baptism is performed with water and dispensed in the name of God, the Father, the Son, and the Holy Spirit.
The water used for baptism is consecrated in the name of the triune God. The baptising minister then uses the consecrated water to make the sign of the cross three times on the forehead of the person being baptised while speaking the words: “I baptise you in the name of God, the Father, the Son, and the Holy Spirit.”
If the baptism is thus dispensed with water and in the name of God, the Father, the Son, and the Holy Spirit (“rite”), it is valid and can unfold to its proper effect.

The designation “rite” is from the Latin and means “in the proper form”, or “conforming to the rite”.
