Trinitarians and non-trinitarians have different beliefs because they interpret the Bible and the nature of God differently. Trinitarians believe that God is one being who exists in three distinct persons: the Father, the Son, and the Holy Spirit. They base their belief on passages in the Bible that suggest the divinity and unity of these three persons, such as Matthew 28:19, John 10:30, and 2 Corinthians 13:14.
They also rely on the decisions of the early ecumenical councils, such as Nicaea and Constantinople, that defined the doctrine of the Trinity in response to various heresies.
Non-trinitarians reject the doctrine of the Trinity and believe that God is either one person or a group of separate beings. They base their belief on passages in the Bible that emphasize the oneness and uniqueness of God, such as Deuteronomy 6:4, Isaiah 44:6, and Mark 12:29.
They also point out the passages that imply a distinction and subordination between the Father and the Son, such as John 14:28, Mark 13:32, and 1 Corinthians 15:28. They also question the reliability and authority of the ecumenical councils and the creeds that they produced.
The debate between trinitarians and non-trinitarians has been going on for centuries and is unlikely to be resolved anytime soon. Both sides claim to have biblical and historical support for their views, but they also have different ways of understanding and applying those sources. Ultimately, it comes down to one’s faith and personal relationship with God.
