Pope: Christians Not True Churches???

Recently, Pope Benedict the XVI announced- (LORENZAGO DI CADORE, Italy)- and "reasserted the universal primacy of the Roman Catholic Church, approving a document released Tuesday that says Orthodox churches were defective and that other Christian denominations were not true churches." according to the associated Press/Nicole Winfield (June 10th, 2007, Time Magazine) http://www.time.com/time/world/article/0,8599,1641666,00.html .
The Pope is isolating the Catholic Church by promoting disunity among Christians. The Bible is the central authority on who is and who is not a Christian. It clearly states that it is not the Church nor its leadership that determines the Salvation of a person but it is by faith that we are saved. Catholic doctrine states that those who are a part of the Catholic Church (in reference to the denomination and not it original meaning Universal) are saved and those who are not of Catholic denomination are not saved. This is heresy and apostasy. The Holy Scriptures state in Romans 10:9 "That if you confess with your mouth, Jesus Christ is Lord, and believe in your heart that God raised him from the dead, you will be saved."
This particular Catholic Dogma is leading people into apostasy (wrong teaching) and possibly heresy, the book of Romans is in obvious conflict with this particular Catholic Dogma. Ecumenical relationship between the Catholic Church and Protestant Churches will face some hardship with this sort of attitude and religious predjudice. I wonder if the reason for this sudden blow to ecumenism is an attempt by Catholic leadership to regain memebers that were lost to other denominations. At a time when the Catholic Church is losing more member than gaining per year, seems to suggest a church that is doing something desperate. To rectify their situation it is possible that they are employing fear as a tactic to keep the members that they in a position to lose or regain members back. I admit that this is only a humble and small political theory about what the Catholic leadership strategy is.
It seems to me that not much can be gained from this. I suggest that both Catholics and Protestants must learn to accept each other as brothers in Christ who worship the God, the same Christ crucified and risen Lord. True Churches are those who put the authority of salvation and judgement in the able hands of the Lord and those who teach anything different are perhaps ignorantly teaching heresy/apostasy at best, or at worst doing it intentionally.
