Dear Mary:

When someone is in danger of death, anyone can baptize them, even an atheist, as long as the person does what the Church intends -- which is to baptize the person who desires Christ with water poured over the skin and in the name of the Father and the Son and the Holy Spirit.

The faith, or lack thereof, of the person doing the baptism is not an issue. The Church supplies the faith needed for the Sacrament. This is also true of a priest. If the priest's personal faith is lost, as long as he does what the Church intends the Sacraments are still operative and valid.

This "proxy" faith takes place when we baptize babies. The babies, themselves have expressed no faith. It is the faith of the parents and the Church that supplies the faith for the Sacrament.

Mormons and Jehovah Witness are not Christians because their baptisms are not valid. In this case neither their "church", the ministers, or the person being baptized believes in the Trinity. Any baptism by a "church" entity that does not believe in the Trinity is not valid.

The Jehovah Witness do not believe in the Trinity and do not baptize in the name of the Father, and of the Son, and of the Holy Spirit.

The Mormons do use the Trinitarian formula, but their definition of the Trinity is heretical. There is no magic in the words. It is the meaning of the words that count.

For example, Mormons think that Jesus and Lucifer are brothers. No kidding!

Jesus told those who used the jargon of the Faith, but really had no faith to depart from him:

(Matthew 7:21-23)  "Not every one who says to me, 'Lord, Lord,' shall enter the kingdom of heaven, but he who does the will of my Father who is in heaven. On that day many will say to me, 'Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?' And then will I declare to them, 'I never knew you; depart from me, you evildoers.'"

God Bless,
