Unitarian Universalism (all religion lead to god) is WRONG because in here, “you are the hero” or that “you are god” in the end.
Christ centered Universalism (Lord Jesus saves all) is CORRECT because here, “God (Jesus) is the Hero” and “we are just creation” (no theosis).

Indeed, there are “many roads” imply:

In Unitarian Universalist’s perspective (WRONG):
“All roads lead to god”

In Christ centered Universalism’s perspective (CORRECT):
“God (Lord Jesus) Himself travels all these roads to seek and find those lost in it”

As He Himself declared:

“For the Son of Man has come to seek and save that which is lost” – Lord Jesus Christ

I’ll give you another ‘key’ reason why Unitarian Universalism is WRONG while Christ centered Universalism is CORRECT:

Unitarian Universalism has duality whilst Christ centered Universalism accounts to God’s Oneness.

What?

Simple, in Unitarian Universalism, we find that contradictory religions & their teachings seemingly united only under a ‘label’ but not in ‘God’. This is evident in that each of the opposite religions co exist in some way but they are NOT ONE in agreeing to ONE GOD and ONE TEACHING.

On the other hand, Christ centered Universalism clearly is of ONE GOD (Trinity), ONE CHURCH (catholic or universal called-out ones or the Ecclesia), ONE PURPOSE (God saves all), ONE FAITH (in Lord Jesus alone), ONE WILL OF GOD (to save the world), ONE RELIGION (take care of widows & orphans), ONE WORD (the Bible), etc…

Now do you understand why it is said, “God is One” in the Bible? Indeed, because He is “literally” ONE in all sense.

No “duality” exists in the True God.
(secret of God revealed).

“Make every effort to keep the unity of the Spirit through the bond of peace.

There is one body and one Spirit, just as you were called to one hope when you were called;

one Lord, one faith, one baptism;

one God and Father of all, who is over all and through all and in all.”

(Ephesians 4:3 – 6)
