‘God-bearing' is too similar to the Greek 'Theotokos,' meaning 'God-bearer,' a title used for Mary the Mother of God. In this way, they are highly implying that they are to give birth to a new God, maybe because the old one is dead or that the old one needs to be dead and replaced, and they will renew the world and humanity will new life and the new ‘word’ - this refers to Christ: ‘In the beginning, there was the Word, and the Word was with God, and the Word was God.’
It’s Kirillov’s philosophy as well. It makes sense that Shatov and Kirillov have similar ideologies, since they spent America together.
