The truth though is that the church of rome has another Gospel, has extra biblical revealtion/authority, so that makes them another bbilical cult, in same boat with SDA!
Correction: that is your truth.
That is not the truth for many Catholics who, as I said, are in large part ignorant of the teaching of the Roman Catholic Church.
If we were to quiz any given denominational fellowship concerning what their Church teaches...most would fail. We see evidence of "Baptists," for example, teaching pre-existing spirits (prior to conception), Annihilation, Soul Sleep, and a number of various odds and ends that could be properly determined to be heresy...all the time.
Just because you want to believe that all Catholics worship Mary, would kiss the Pope's ring, and deny Eternal Salvation...doesn't mean that they do. If it makes you feel better as a Christian to have someone to look down on, have at it. Me, I am going to find out what any particular member of any particular group believes before I comment.
Paul is a great example of fervor and zeal for the indoctrinated religion one is born into, and how GOd can convert a person to the truth. You will never be able to speak to Catholics while holding such a belligerent view, and the question is...
...do you care for those who, though religious, may be lost.
And I don't think I have ever heard a Catholic make the statement that before the Incarnation "Jesus was just the Son of God."
In regards to SDAs, their view of a prophetess being a legitimate source of revelation is not really any different than the views of many Charismatics, who also believe that revelation is still being given. But do we take that to mean that every Charismatic is lost, and that not one of them sincerely love God, and do what they can in the capacity they have?
As I said, I do not view the Catholic Church as a cult, but as just another religious group with various errors, and all error is serious. I don't think God will condemn the Catholic for "worshiping Mary" any more than He will condemn the Baptist for worshiping their Pastor.
God understands their ignorance, and the source of their ignorance. We should do the same, first examining our own selves.
God bless.
