I would add that Episcopal bishops are in the line of apostolic succession. When the English church separated from Rome, it had a coterie of bishops who had been ordained as successors to the apostles and maintained apostolic succession in ordaining new bishops.  Following American independence, there were no bishops. Samuel Seabury was elected bishop and went to Scotland for consecration by a bishop of the Scottish Episcopal Church. (He chose Scotland because there was no requirement there, as in England, to swear an oath the King.)
