I was talking to a Lutheran who made the claim that Lutheran’s also have an apostolic line, since Luther was once a priest.
I have also heard apostolic Succession used by Anglicans, however, I am not sure why they believe that, as King Henry was never in the clergy.
Finally, I do not understand how IF lutherans do not have apostolic succession, that the Orthodox churches do.
For a valid ordination, you need
- the minister - a validly-ordained bishop,
- the matter - a validly-ordained priest
- the form - the essential prayers, laying on of hands, and perhaps anointing with sacred chrism
- the intent - to ordain to the ministerial episcopate.
Luther could not have ordained anyone, since he was not a bishop. If a Catholic bishop had become Lutheran, he could have ordained other bishops. As far as I know, the Lutheran lines of Apostolic Succession died out, either from lack of form or intent, or they just might have stopped ordaining bishops. Scandinavian Lutheran lines might still be intact.
Anglicans had lost their Apostolic Succession because of a lack of form and intent, as determined by Pope Leo XIII, linked by a previous poster. That document was valid for the time that it was published, and for the putative bishops that it covered. In other words, it did not preclude the Anglicans regaining Apostolic Succession from another valid line.
The Communion of Utrecht, or Old Catholics maintained Apostolic Succession. Since they started celebrating ordinations in union with the Anglicans, valid Orders might have been restored. I do not know if Rome has spoken on whether they have. However, any ordination that the Anglicans or Old Catholics might attempt on a woman are invalid, as she is not valid matter, regardless of who is performing the rite. Consequently, if she then tries to ordain someone else, it will not be valid from her.
The Orthodox Churches maintained Apostolic Succession through proper form and intention, and only on valid matter by a valid minister.
Holy Orders are not lost by heresy or schism, but can only fail to be handed down through a defect of form, intent, or matter.
