I'll reason with you. Father, son, holy spirit. To most Christians they form up like voltron and make up one without it making sense. How many people have you met that are their own sons. How many fathers do you know that are their own sons? How many sons do you know that are their own fathers?
When the Jews' hearts were hardened against Christ, the vicar spilled over on to the gentiles and god created a New Covenant thus giving up on the Jews finally who were so wicked and so awful.
