Why does the Seventh-day Adventist Church believe in the Trinity?

Answer 1

According the official Adventist theology, yes. However most Adventist members are Tri-theist, i.e. they believe in a God-Head consisting of three individual and separate Gods who are one in purpose but not one in actuality.

Answer 2

They ( Seventh-day Adventists ) do NOT believe in the Trinity. This is explicitly demonstrated in their teaching that Christ could have sinned and lost His salvation. The teaching goes past this affirmation and continues to the point where it's promulgated that IF Christ sinned God would have eternally annihilated Christ and He would have become as if He never existed in the first place.

Unfortunately the above theological affirmations remove the possibility of SDA's claiming they believe in the Trinity for the Trinity affirms that Christ was ( and is ) the same yesterday, today & forever.

In addition to that Jesus was very clear that "ALL" of what was said about Him in the Law, Prophets and Psalms HAD TO BE FULFILLED. That 'God' would Himself come and save us and that He would not participate in any sin was a huge part of what the Old Testament said about The Christ.

So, in answer to your question the Seventh-day Adventist Church does NOT believe in the Trinity...

...They have opted to go with a creature Christ that was giving "conditional deity" by the Father or Ultimate God.

Answer 3

Adventists believe in the Godhead. Which is composed of 3 personalities that are always in agreement. God the father, God the Son, and the Holy Spirit of God.
