One of the doctrines that make Christianity unique is the doctrine of the Trinity. We worship a God who exists as three distinct persons, all having the same essence. In other words, the God we worship is 3 "who's", 1 "what".
This can be a difficult concept to comprehend!

What is "Modalism"? Listen and find out! We're excited you're here with us today, let's get into it!
