Did Islam Preserve the Original Teachings of Jesus Better Than the Church?
If Jesus preached the Trinity as the core truth necessary for salvation, why do his earliest recorded teachings focus repeatedly on pure monotheism, obedience to God, repentance, prayer, charity, and submission to the Father, while the fully developed doctrine of the Trinity only emerged after centuries of theological disputes and church councils?
Jesus said:
«“The Lord our God, the Lord is One.” (Mark 12:29)»
He prayed to God.
He called the Father “the only true God” (John 17:3).
He said:
«“I can do nothing by myself.” (John 5:30)»
He distinguished himself from God repeatedly:
«“My Father is greater than I.” (John 14:28)»
Meanwhile Islam teaches:
- One eternal God with no partners
- Jesus as Messiah and prophet
- Virgin birth
- Miracles by God's permission
- Prayer, fasting, charity, modesty
- Submission to the will of God
In other words, Islam appears to preserve the actual theology and lifestyle of Jesus more consistently than later post-Nicene Christianity.
So my question is:
If a first-century follower of Jesus met:
A modern Trinitarian Christian who says God became a man, died, and is one essence in three persons
A Muslim who worships the One God alone, reveres Jesus as Messiah, prays like Jesus, fasts, gives charity, and rejects worship of creation
Which of the two would resemble the original teachings of Jesus more closely?
And if the Trinity was truly taught clearly by Jesus himself, why is there no explicit statement from Jesus saying:
“I am God, worship me,”
or:
“God is three persons”?
Why did later councils need centuries of debate to define what salvation supposedly depends upon?
