His invitation may or may not be accepted by individuals, that is up to them. Your question of how it relates to YOU is apples and oranges. An Ordained Priest has studied for many years to get where he is, so transferring is more a matter of learning the specifics of rules that apply to one rather than to the other.
Therefore, it does not take years. Remember, Episcopalians ARE Catholic. We are part of God's Holy, Catholic and Apostolic Church.
Just because the Roman Church calls itself 'Roman Catholic' has nothing to do with the other Catholic Churches, of which the Church of Rome is only the most often in the news, therefore the most 'famous'. As an Episcopalian, you are Catholic. This is just a transfer from the Church of England to the Church of Rome, and has actually been common, in both directions, for decades, just rarely spoken of until the Bishop of Rome went on the television about it.
There are some very detailed rules around this, and the actual number of people who are going to take up this "offer" is actually rather small. I was raised Roman Catholic and became Episcopalian more than 25 years ago, because I couldn't assent to such required dogmata as Papal Infallibility and the Immaculate Conception (which is _not_ the Virgin Birth, which I have no problem with.) We do accept divorced and remarried people; we ordain women and married people; and we elect our bishops. And we have traditional liturgy, high-quality preaching, and serious lay adult education.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
