Thank you for confirming that. I certainly wasn't aware of any difference, but it's still nice to be certain.
There are certain doctrinal differences between Reformed, Catholic and Orthodox Christians, but there are also certain core beliefs where we have 100% agreement and the Holy Trinity is one of them.
I like xone’s point which asks, if I may paraphrase “so, if they want to believe in three modes instead of the trinity we believe in, as long as they affirm that Christ is the way, should we let them be”? And I agree — if Uri or Iscool or roamer_1 truly and sincerely believe in what they believe in, that’s their free choice. We can explain why we believe what we believe and so can they. I won’t insult them for that belief and I hope they extend the same courtesy in return.
