chaela,
Historians have nothing to do with it. Historians do not construct theology. The Church Fathers and what has been consistantly, from any part of the world, from any century it has remained the same. It is putting your faith in the Holy Spirit, In Christ and the promise made to ensure that the Once Given Gospel remains, that the Body of Christ shall remain.
the problem with the RC is that it has been led by a single man with a magisterium that dictates what they Church will believe and what it will practice for 1000 years. Changes have been made along the way that drastically has changed the meaning of the Original Gospel. Most changes were made on the suggestion of a person or a very small number of people. Some were made with out any reason to make them, just that something aught to be changed.
What you have done is moved from the pot into the fire. Now, instead of a man or magisterium you depend on your own ability which is as fallible as any other human. You also depend on a book that is now isolated from its full content and context in order to determine what kind of faith you shall have or believe.
Unless you would like to claim to be an original Apostle. And claim that for some reason it has never been believed and taught before but now we have some authentic evidence that the Apostles did indeed teach Universalism. It would turn on its head what has always been taught and beleived. It would mean that the Holy Spirit failed to give us ALL Truth in the beginning and has been unable to preserve that teaching from the beginning.
One must be careful in how terms are used. Universal reconciliation does not mean Universalism necessarily. I also believe in universal reconciliation because that is precisely what Christ did on the Cross in redeeming His creation. That is precisely what Col 1:15:20 is saying, But this has nothing to do with the fact that the Church has always believed in a hell. That not all men will be soul saved. These are two separate issues.
It may be an ongoing debate, but history is quite easy to follow as to which is correct.
