Well, since Yeshua declared that his assembly doesn’t have any denominations, buildings, nor wealth, it has to be non-denominational!
Yeshua’s belief and practice is simply Torah, so that shouldn’t be so hard to determine.

Christ's Church is not a denomination, it's the Catholic Church.
I know you disagree.
But the topic here is whether there is evidence for the existence of what was claimed, excluding the Catholic Church:
Non-denominational Christians since the time of Christ specifically those claimed to be ancestors (in belief and practice) to current non-denominational Christians unbroken in history up to the present day.That's the question. One can assert they existed, but it is just an assertion without evidence.
