Some forms of Gnosticism assert this.
Gnosticism is a broad group of early Christian cults that are influenced by earlier religions, so it's not a monolith and I don't want to paint them with the same brush, but:
Some of them include the idea that our souls (our consciousness) are from a realm or being of light, but the material/physical world was constructed by the demiurge (yahweh of the old testament) and has trapped us here.
According to this idea, Jesus is actually from that divinity beyond Yahweh, and is not the son of God. So Jesus' sacrifice was not just the crucifixion, but embodiment itself. He brings us knowledge (gnosis, thus gnosticism) of our true divinity and through that knowledge, salvation from this material prison.
There's an amazing book about all this, called, The Gnostic Religion, by the philosopher Hans Jonas.
