True or false? The Holy Trinity is a man made concept.?

oh why not I will drink to that...but not on SUNDAYS

The concept of the one, triune God was in the Bible from Genesis onwards. Father, Son and Holy Spirit all created everything – Gen 1:2 Isa 44:25 John 1:1-3. Yet Yahweh declares that He created everything by Himself – no-one was with Him – Isaiah 44:24 & 48:13. But Jesus said that His hand and His Father’s hand are one and the same Hand – John 10:28-30 cf Is. 49:16.

The Father resurrected Jesus – Acts 2:24 2 Cor 4:14. Jesus raised Jesus – John 2:19-21, 10:18. The Holy Spirit raised Jesus – Rom 1:4, 8:11.

Yahweh denies there was any god either before Him or after Him – He recognizes no other god – Isa 54:5, 21. Yet Jesus is ascribed deity in the Bible – John 1:1 and Yahweh tells all angels to worship Christ – Heb 1:6. So either Jesus is a false god or a usurper god or God – the same God – the Only God. And Jesus ascribes deity to the Holy Spirit by saying Jesus can be spoken against and that person forgiven but no blasphemy against the Holy Spirit will be forgiven – Matthew 12:31.

All who turn to God to be saved, bowing to Him, is turned into turning to Jesus to be saved, bowing to Jesus – Isa 45:22-24 cf Acts 2 and chapter 4 and Joel chapter 2. See Philip 2:10-11, Rom. 14:11. But nobody can get to that point of being saved without the initial work of the Holy Spirit in them, as Jesus said, Jn 16:7-15.

Only God is the Saviour but then Jesus is also called the Saviour – Isa 45:21 cf Lk 2:11. Rev ch. 5 speaks of all heaven worshipping Him who sits on the throne AND the Lamb at the center of that same throne in Heaven. And the seven-fold Spirit is surrounding that throne.

Doubting Thomas declared of the risen Christ, “My Lord and my God!”, Jesus accepting that worship Jn 20:28. Stephen prayed to Jesus, whom He had seen in vision alongside the Father. Why did he not pray to the Father? Because Jesus had told the Christians to ask HIM for anything, in His name, and He would grant it – Jn 14:13-14. Stephen committed his spirit to Jesus as he died – Acts 7:54-60.

Really, I could go on and on, listing very many more scriptures but to deal with your Q but here's the point. The doctrine is utterly biblical. The finished form of theological words to boil that all down to one doctrine took a while to thrash out, being required in order to refute heretics like Arius who taught that Jesus was only an angel - a creature. We have all his modern-day supporters piling in here to deny the Trinity doctrine.

Man-made, as is religion, gods, spirits, devil, satan, etc.

Ita a man made concept.

The question is nonsensical. The bible is man made concept. The idea of a god is a man made concept. See where this is going?.......

God is a man made concept, but the concept of the Trinity is in the bible, which is why the Trinity eventually came to be. The bible mentions the Father, Son and Holy Ghost/Spirit. The bible mentions that "three" bear witness in heaven. John says Jesus is God. All the ingredients are there to form the Trinity concept, but all of it is man made.

Of course it is........ All religion whichever you choose is a man made concept

Only for those who can't count to three. We are told to baptize in the name of Father, Son, and Holy Spirit = 3 = Trinity.

False.  The concept of a triune God is Biblically based.

True.

All religions and religious texts etc are Man Made.
