What are the key differences between non-Nicene Christianity and mainstream Christian beliefs?

Answer 1

Non-Nicene Christianity refers to Christian beliefs that do not adhere to the Nicene Creed, which was established in the 4th century. The key differences between non-Nicene Christianity and mainstream Christian beliefs lie in their interpretations of the nature of Jesus Christ and the Holy Trinity. Non-Nicene Christians may have varying beliefs about the divinity of Jesus and the relationship between God the Father, Jesus, and the Holy Spirit, diverging from the orthodox views held by mainstream Christian denominations.
