Born and baptized into it, confirmed, by the grace of God.
So you never chose your faith? What would Luther think of you?
Anyways, in all seriousness, you have not been Anathemised. Luther was.
His followers who chose to turn their back on the Church, were also anathemised. This is only after they persisted in attacking the Church and her believers long after Trent.
The door is open, it always has been. Those who through their own sincerity have found themselves on the other side, are Christians no less and no more than the rest of us.
Trent is not abrogated. Trent assessed the question as to who was correct? The Catholic or the Protestant understanding. Luther, Calvin, all the reformers were invited to make their cases before the council, as the Arians, and the monothelites had done previously.
As Luther himself had even called for an ecumenical council.
There were 25 total sessions, each of them dealing with separate questions raised by Luther and Calvin and Zwingli.
If you want the full and formal list, let me know.
