I got the original story here: Beggars All: Reformation and Apologetics: Pope Making Friends With 75 Million Reformed Christians

First, I think it's important to note that the partnership with Rome involves social justice, not doctrine.

And that when Bishop of Rome talks about ecumenicalism, he means that he wants to bring all protestants back under the leadership of the Roman Catholic Church.

We are "separated brethren". Referring to the Roman Catholic faithful, Vatican II says, "Their ecumenical action must be fully and sincerely Catholic"

Also in Vatican II, "Though the ecclesial Communities which are separated from us lack the fullness of unity with us flowing from Baptism..." (my take on this - ok...we're saved, but we're not that saved)

Vatican II says that "The children who are born into these Communities and who grow up believing in Christ cannot be accused of the sin involved in the separation, and the Catholic Church embraces upon them as brothers, with respect and affection. For men who believe in Christ and have been truly baptized are in communion with the Catholic Church even though this communion is imperfect." (Again, we're saved, but Christ's finished work on the cross isn't finished unless we're under the leadership of Rome)

Bishop of Rome, Benedict XVI said, in his first messages as Bishop of Rome, "But what is most urgently needed is that "purification of memory", so often recalled by John Paul II, which alone can dispose souls to accept the full truth of Christ." (Who has the "full truth of Christ"? According to Rome, the Roman Church is the church that has the full truth)

My questions are: Whose memory needs to be purified? What do they need to forget in order to "accept [Rome's] full truth of Christ"?
