While I understand what you are saying... Buddhism and Christianity are not mixable... Actually, they seem to be contrary to each other... Not sure how you came to God through Buddhism, but I guess maybe that was just a stepping stone to reality...
I’m not a syncretist, but there are similarities among major religions. Those who look in the same direction find similar things.
IMHO, among the other religions, buddhism the closest to Christianity in many ways.
I am Christian not Buddhist now. “Mixable”? No. But much of what I learned during my time in buddhism has been valuable in my spiritual, hopefully, growth as a Christian.
