Very bad news for you: it's doctrine, not discipline.

Confirmation, Eucharist, Reconciliation, Unction, and Orders can only be administered by a validly ordained bishop or priest, Orders only by a bishop.

The Church has faced this issue many times, most recently in the West in the Protestant Revolt, and the Catholic, Orthodox, Oriental Orthodox churches all agree.

In the case of the Catholic Church, this was formally declared at the Council of Trent.
