There was a man who was burned at the stake at a young age. His name was Michael Servetus.
The following is a copied summary from a searched source.
Michael Servetus was a Spanish theologian, physician,
and humanist who is well known for denying the doctrine of the Trinity.
During the Reformation era, he was condemned as a heretic by both Catholics
and Protestants and was executed.
He believed that the traditional doctrine of the Trinity lacked sufficient biblical foundation.
Rather than viewing Jesus as the eternal Son of God,
he understood Him as God manifested in human form.
He emphasized a humanistic faith that called for a return to the Scriptures,
but this sharply conflicted with the orthodox doctrines of his time.
He was first arrested by the Catholic Church but managed to escape.
Later, in Geneva, Switzerland, he engaged in theological disputes with the Reformer John Calvin.
Eventually, in 1553, he was burned at the stake by the authorities of Geneva.
Heretical Jehovah’s Witnesses insist that there is no Trinity,
because they believe that Jesus is a created being an angel created by Jehovah.
Catholics, Protestants, Seventh-day Adventists,
and other denominations insist on the Trinity because they believe Jesus is the eternal Son.
The Church of God, and the Unification Church also claim the Trinity.
They do so with the intention of placing themselves in the position of the Holy Spirit
and leading people to believe that they themselves are God.
Those who advocate Modalism also claim to believe in the Trinity.
They think they believe in the Trinity.
The Trinity is one body with three heads; Modalism is one head with three bodies.
All of them refuse to give up their respective claims. Yet all cry out, “Lord, Lord.”
Yehowah God has spoken:
“I am the Lord, and there is no other; apart from Me there is no God.” (Isaiah 45:5)
That gospel is the gift of the Father Yehowah God who became man and rose from the dead.
“For by grace you have been saved through faith, and this is not from yourselves;
it is the gift of God.” (Ephesians 2:8)
