The Emblems of Religion don't belong ... or do they?

[HerenIstarion]

Eru could as easily be One, as in other branches of Christianity

There is no branch of Christianity I'm aware of which does not accept the concept of Trinity

The concept of Christ's nature is where views may differ (Was He human or God by nature, or both. Most part of Christians believe that both)

And yet, here we all are, looking for them.

Not them exactly, I surmise. Slips of the tongue (conscious in the revision, no doubt ), as mentioned, mainly.
