The choice of words one uses for "marriage" should be the main focus.who="Anthony MN"
You have wedding ceremonies in the pentecostal community no? Your preachers have certain requirements for the couples, i.e., he verifies they aren't married to someone else, they're sincere in their desire to wed, etc.?
Why do you believe a pentesoctal preacher can make certain determinations and the Catholic Church can't? And quit making assumptions as to someone's guilt before you know the real story. No one exonerated anyone, people are turned down in their anullment applications all the time.
The Pentecostal preacher does not consider a Catholic marriage to be invalid.
Catholicism considers marriage as a sacrament, other sects don't, but just an action that takes place between two people.
But if one is to reference your statement of:
"The Pentecostal preacher does not consider a Catholic marriage to be invalid."
A Pentecostal preacher does not consider a same sex mariage to be valid, yet it is in 10 states.
You are now starting to sound hypocritical - based upon qualifiers.
