I don't know if it would be considered spiritual charity or an act of spiritual aggression. The implication of the baptismal work (sometimes on already baptized deceased Christians) is that the deceased person's religion or faith was insufficient to gain them entrance into heaven. That's what people are probably reacting to. My religion is more powerful than yours yada yada.
Personally, I would rather people not pray for me unless my spirit is in agreement with the desired outcome of the prayer, like, you know, the bible verse which says, "If two or more of you *agree* on touching any thing . . ." The *agreement* is sometimes lacking in certain forms of intecessory prayers or works which may be construed as not respecting a person's spiritual boundaries.
Then there is a possible occultic aspect of the whole business. Who really knows what powers from which realm are unleashed in some kinds of prayers or religious works? We have very specific directions in the bible to agree and to ask the Father in Jesus' name. If people pray for an outcome or to a deity with which I do not agree for me or mine, I would rather not have the prayer.
I have no objection to anyone of good will participating in the generic or specific kinds of charitable and healing prayers on this forum for living persons, and in the case of the deceased only that they are in peace and will reach heaven, the real heaven spoken of in scripture, not a reinvented heaven on the part of a reinvented religion that does not square with everything that Jesus taught.
Yep. That's pretty much the way most religions see it, isn't it?
That's why Catholic and Protestant missionaries have been preaching around the World for centuries.
Maybe the Athenians had the right idea. As mentioned by St. Paul, the Athenians had erected a temple to "The Unknown God". The Athenians ensured they had all their bases covered.
