Don't you support..
1.) An artificial class of celebate priests?
It's not artificial--it's straight from the NT--and not all our priests are celibate (note spelling).
2.) Belief that prayer to inidividuals (dead or alive) other then the trinity is effectual?
Depends on how you mean "prayer to." No, we do not pray to individuals as we pray to the Holy Trinity.
We DO however ask any Christian, living on earth or in Jesus' presence, for prayers.
3.) Belief that Mary has some sort of role in salvation?
Didn't she sort of give birth to God the Son? So, yes.
4.) Belief that man can appoint 'saints' that God will abide by.
No. God makes them saints. We simply recognize that.
5.) Belief that the Bishop of Rome is the head of the church.
I'm Orthodox, so no--if by "head" you mean universal jurisdictional authority.
Of course, if, as I suppose, you mean "head" in the sense of Christ, then, no, again, only Christ is head of the Church, his Body.
6.) Belief that Mary is a perpetual virgin?
Of course. I'm on record there. It's the undisputed ancient belief of all Christians.
7.) Belief that priests have the power to forgive sins or are some sort of mediator.
No. Let me quote from the rite of reconciliation: "O Lord God of the salvation of Your servants, merciful, compassionate and long-suffering; Who repents concerning our evil deeds, not desiring the death of a sinner, but that he should turn from his way and live. Show mercy now on Your servant [name] and grant to him (or her) an image of repentance, forgiveness of sins and deliverance, pardoning all his (or her) sins, whether voluntary or involuntary. Reconcile and unite him (or her) to Your Holy Church, through Jesus Christ our Lord, to Whom, with You, are due dominion and majesty, now and ever and unto ages of ages. Amen.
May our Lord and God, Jesus Christ, by the grace and compassion of His love for mankind, forgive you, my child, [name], all your transgressions. And I His unworthy Priest, through the power given me, forgive and absolve you from all your sins, in the Name of the Father, and of the Son, and of the Holy Spirit. Amen."
Of course, this is nothing more than the fulfillment of Jesus' promise in John 20:23.
8.) Belief that there is some sort of festival or holy day structure that believers are to follow?
Of course. Just as they did in the NT.
9.) Believe that the lords supper is something other then a time of remembrance.
Of course, don't you? It's a NT doctrine and practice: see John 6:53-57, 1 Corinthians 10:16-17 and 11:17-34.
If you believe any of the above we really dont have much to talk about because they are all anti-scriptural and looked at as heresy by the protestant church at large...
Actually, as I've shown, they ARE Scriptural and if the Protestants see them as heresy, well, then the Protestants are anti-Scriptural, aren't they?
