The Catholic Church has 'babtism by Desire'. . .implying that if one leads a good life; one that follows spiritual Principle. . .then that person earns a 'Babtism of Desire'. . .this is how they reconcile the delemma of those of other 'Faiths' i.e. Jews/non-Christians; or just un-babtised 'Christians' who otherwise would be excluded, can be spiritually sanctioned to enter Heaven.
See 'Babtism of the Dead' as perhaps a similar concept.
Can we just appreciate people. . .political leaders who live a 'moral life' and one that is honorable. . .who are perhaps both 'God-loving and God-fearing'; without a Christian Bible litmus test?
Certainly have fond memories of the Bible-carrying Clinton's doing their 'entering and exiting' photo-ops. . .
I don't know of any faith that practices anything called "babtism".
