Now wait a second. As the beloved prophet John Wayne (Hallowed be his name) said, “Hold your horses”.
I am an ordained minister in the ULC (Universal Life Church - I know it sounds like a life insurance policy gig - but I did pay like $75 for the full Reverend package), does that make me non-Christian.
In truth, there are Jewish Christians, Hindu Christians, Scientology Christians, Latter Day Saint Christians, secular Christians, Wiccan Christians, Islamic Christians, even female, gay and black Christians (NOOOOOO! )
I don’t think you can pigeon-hole anybody into anything. There are literally 8.3 billion religions in the world right now. Your perspective/interpretation of God, Christianity, atheism, creationism, Jainism, Buddhism, Judaism, Islamism, feminism,… is completely different than mine.

Summary: A person can be a “Jewish Christian” if they are ethnically Jewish by heritage but Christian by religious belief, or if they belong to modern theological movements like Messianic Judaism which deliberately blend the two practices.
