The RCC teaches that its priestcraft are made up of men who are an "alter Christus," "another Christ."
Blasphemy, no matter how Rome tries to spin it.
Which men do Catholics think have a right to create doctrine out of men's opinions?
Various popes. For 1800 years Mary was not said to have been assumed into heaven bodily. Then some pope gets it in his head to declare the "Assumption of Mary" as doctrine.
Christianity does not rely on fallible men for its doctrines. Christianity relies on God's word alone.
For the one millionth time, your marginal English skills and a link to an errant priest do not constitute Catholic dogma. The priests act in the place of Christ during the Mass, not unlike James Caviezel in The Passion of the Christ. No one believes he actually is Christ and no one says he is unless they are misinformed or lying.
What is "priestcraft"?
See, the definition of terms is so important...sometimes I think we are not speaking the same language. Nobody worships priests, they are men. Nobody worships humans, including the saints. Nobody thinks they are God, why do you say that?
For 1800 years, Catholics believed Mary was assumed into heaven. It wasn't formalized until Pope Pius XII. But way back in the very early church it was believed and taught.
If what you call Christianity relies on God's word alone, what if you disagree on interpretation or translation? How do you solve that?
