Episcopalians claim Apostolic Succession too, which they have in a physical sense. Which leads to something that's bugged me a little. The only reason the Anglicans do NOT have Apostolic Succession is because a Pope, long after the death of Henry VIII, SAID they didn't have it. But how can anyone, even a Pope do that? They can't take away orders anymore than they can allow divorce. The Ordination is a Sacrament just as Marriage is a Sacrament, and what God has joined (ordained) let no man put asunder.
That is an interesting question, but once the English Prelates removed themselves from the Authority of the Roman Catholic Faith, the laying on of hands was no longer valid. Their are some groups in the Orthodox Church that are in the same situation. The Anglicans have the historical continuity, but the spiritual gifts were lost when they placed themselves out of the authority of the Western Church. Besides, Anglicans are not even sure what they believe, it changes from one person to another.
