Correct - the Bahai texts do not say that the world is created by the Manifestation, but through the Primal Will: " by His wish, which is the Primal Will itself, all have stepped out of utter nothingness into the realm of being, the world of the visible. "
and the Manifestations are ""the Focal Point of God's Primal Will." "this Primal Will which appeareth resplendent in every Prophet and speaketh forth in every revealed Book."
Equally, the Christian texts do not say that Jesus created the world, but rather that Jesus is "he through whom all things were made." and "In the beginning was the Word, and the Word was with God, and the Word was God. .... All things were made by him; and without him was not any thing made that was made," and that this Word speaks through Jesus and the Scriptures and the Church.
You're on a different wave length. You are trying to wrest agreement between Baha'i and Christian concepts that are poles apart.
There's nothing you cite from Baha'i texts that say your god creates 'through' the manifestations, but rather through the 'primal will' (whaterver that is).
The Word doesn't speak
through Jesus. The Word
is Jesus
John 1:1 says that the Word was there at the beginning. And John 1:14 says that the Word became flesh. That is, Jesus.
Jesus was there at the beginning.
Colossians 1:16 says that things were created by Jesus. Not just 'through' Jesus.
Christians don't say that Jesus is but a manifestation of God, but
is God. They are of the same nature!
They are one
I John 5:7
There are those that bear record in heaven: the Father, the Word, and the Holy Spirit: and these three are one
Philippians 2:5-7 "Your attitude should be the same as that of Christ Jesus: Who, being in very nature God, did not consider equality with God something to be grasped, but made himself nothing."
Jesus said in John 10:38
But if I do it, even though you do not believe me, believe the miracles, that you may know and understand that the Father is in me, and I in the Father.
They are of one accord
John 5:21
For just as the Father raises the dead and gives them life, even so the Son gives life to whom he is pleased to give it.
Jesus is equal to God
Colossians 1:19
For God was pleased to have all His fullness dwell in Him
Jesus has the power and wisdom of God
1 Corinthians 1:24
...Christ the power of God and the wisdom of God.
Jesus is eternal like God
Hebrews 13:8
Jesus Christ is the same yesterday and today and forever.
Colossians 2:9
For in Christ all the fullness of the Deity lives in bodily form
This is reflected in the writings of the early church, such as Ignatius of Antioch's opening address to his Epistle the Romans
Ignatius, who is also Theophorus, unto her that hath found mercy in the bountifulness of the Father Most High and of Jesus Christ His only Son; to the church that is beloved and enlightened through the will of Him who willed all things that are, by faith and love towards
Jesus Christ our God; even unto her that hath the presidency in the country of the region of the Romans, being worthy of God, worthy of honour, worthy of felicitation, worthy of praise, worthy of success, worthy in purity, and having the presidency of love, walking in the law of Christ and bearing the Father's name; which church also I salute in the name
of Jesus Christ the Son of the Father; unto them that in flesh and spirit are united unto His every commandment, being filled with the grace of God without wavering, and filtered clear from every foreign stain; abundant greeting in Jesus Christ our God in blamelessness.
