It is great when terms such as "Orthodox" and "Catholic" are being used in their true and proper meaning as opposed to the highjacked association with the "Eastern Orthodox" and the "Roman Catholic" denominations. The true Church of Christ is Orthodox in its teachings and universal in its existence, and Christ is the Head of the Church. Amen!
I am a wholehearted member of (and officer for) the [Orthodox Presbyterian Church](https://opc.org). Given the rise of Eastern Orthodoxy in the West, I am often asked what that 'Orthodox' means in the name of our denomination?
Here is a helpful answer: ["Orthodox" Revisited - Part 3](https://opc.org/qa.html?question_id=37). In sum:
- strictly etymologically, it means "right worship"
- in this use, however, it means 'right teaching" and was chosen in contradistinction to the Modernist-ridden mainline Presbyterian denomination out of which "we" were thrust in the early 20th century. There was an earlier name chosen, but the mainline & Modernist Presbyterian denomination actually _sued_ "us" over it for being "too similar." So, as a bit of a cheeky response, "we" said--"OK, fine: so you guys can be the 'Presbyterians'--and (since we have not moved away from the actual doctrines of the historic, Protestant, and Presbyterian church) we'll be the 'Orthodox' Presbyterians." (ha!)
- No, it does not bear any relation to the 'Eastern Orthodox' denomination / tradition _per se_ , though we certainly share with them agreement on the early Ecumenical creeds, etc.
Discussion
Amen. I like to playfully rib my _Roman_ catholic buddy about being a _Protestant_ catholic. Always raises an eyebrow of those within earshot.
(I'm great fun at parties.)
