Just like in everything else, our PRACTICE is an outgrowth of our FAITH.
When the Faith is true, the practice will be an authentic representation of it. When the faith is corrupted, the erstwhile practices might endure for a time, but eventually, they will fall into corruption abuse, misuse, and abandonment.
This has been happening to Baptism for the past 500 years. Protestants continued to baptize their children for a few hundred years after Martin Luther, but eventually started changing the words, and losing the intention. Now, it seems to be very commonplace for protestants to think of baptism as merely an initiation ritual that has as its sole purpose the SYMBOLIC joining of a person to a 'faith community' -- such that it's like a Shriners or Lyons Club or Freemason initiation ceremony.
Even Jєωs today practice Bar-Mitzvah and Bat-Mitzvah because it's a way of being aware of Jєωιѕн roots, and it has no bearing on religion or faith in any way whatsoever. If they're our "elder brothers in the faith," then why would we not imitate their attitude toward religious ceremonies?
But even though baptism has been under such ideological assaults, it still holds true that anyone baptized by a non-believer (a pagan, an atheist, a protestant, a Buddhist, a Zoroastrian), is still really baptized, provided that 3 things are present:
1) The proper words were said, that is, "I baptize thee (or you) John / Mary (the name of the baptized should be said, but it is not essential to say the name), in the name of the Father, and of the Son, and of the Holy Ghost."
2) The proper intention was in mind, that is, to do what the Church does or teaches.
3) Natural water was poured over the forehead of the candidate, enough to run over the skin as the words were spoken, and the water was poured by the same person who spoke the words of baptism.
There are a lot of ways of getting this wrong, but it is really so simple, that one would have to have an ill intention to get it seriously wrong. God did not make baptism difficult to do. Any uninformed person can do it, if they follow simple instructions. The fact that so many abuses are being reported is sort of a proof at how much the devil hates it when baptism is effective.
For example, how much easier it is for the devil to fight against the silly and subjective 'institution' of 'baptism of desire' than it is for him to fight against the practice of water baptism!
