Actuallty I said that Ratzinger SEEMS opposed to this. This is what he actually said... I dunno... how do you take this?
"The lives of these saints show us how in the Church of Christ there is a unity in truth and a communion of grace which transcend the borders of any nation. With this in mind, I pray in particular that Gods will may be done by all those who seek that unity in the truth, the gift of Christ himself."
Unity in the Church is via grace through adhering to the truth, not from belonging to a national Church, such as the Anglican communion.
As the Anglican Communion in America, Canada, Australia, New Zealand, and Britain has departed from the truth, the words are an invitation on the part of Catholic Anglicans to seek unity with the See and lands from which their faith and tutelage in the truth sprang up from, rather than attempting to adhere to a national Church now wracked by multiple errors.
A prayer that God's will may be done in this regard is a reference to the will of Christ "that all may be one".
