You’re probably one of those ex-protestants who joined the Orthodox Church because your pride would not allow you to consider the Catholic Church.
You can tell by the gargantuan stupidity of your claim. It is still steeped in non-Catholic drivel.
BOTH the Orthodox and Catholic Church HAVE Apostolic succession. Both are Holy. But only ONE has a point of UNITY which makes it ONE. A little hint will be that one is called the Catholic Church, and the other is the Orthodox Church.
I’d advise you go read something useful.
