You attenmpt, and fail miserably, to analyze Christianity, yet fail to include what Christianity is.
It is Jesus Christ, the Son of God....
...crucified and risen for us.
Your socio-cultural methodology is mere absorption of the high priests of secular academia.
You can’t analyze Christianity without the focus being on Jesus the Christ. Well, you can, but it is useless.
