Yeah, this is one of those english translation things. A priest is simply an elder and the bishop is the overseer (1 tim 3:2). The scripture also says to call no man teacher in verse 10 of that same chapter, but scripture is clear that this is a gifting and refers to several people as teacher.
I think the biggest hurdle for me when looking at orthodoxy was understanding that these guys arent just a bunch of enigmatic sand hippies, worshipping dead people and their petrified limbs, doing weird stuff because they love heresy. These people truly love Jesus and have a historic basis for literally everything they do, pray, and believe. Many things were difficult to grasp at first but I wanted to give them the honest benefit of the doubt before judging them as incompatible with true christianity. Turns out, they hold the scripture arguably in higher regard than post modern christianity does in my opinion, as they were the ones responsible for compiling it lol
