Why would you need to call yourself anything?
First it is not only Christianity who follow Jesus teachings. Not that I am saying to change religion. It is only to show that Christain are not the only one.
Further more, I have knowned many people who follow Jesus teachings and believe in God but do not take part in any particular religion. Spirituality is a personnal thing to start with. You relationship with God is yours and yours alone.
Jesus was a very wise man and a teacher. I do not see any need to be part of a religion to listen to is wise words. I for one listen to many such wise teachers and do not follow any religion. What do I call myself, nothing at all Only a spiritual person who listen to wisdom and love and strive to always be a better person.
The problem is that if you choose to call yourself Christian, then you have to take everything that comes with it, the good and the bad. Same thing if you do not.
If you call yourself Christian, those who do not believe is this religion or no religion will question you and will not be afraid to let you know how they see Christianity and will wonder why you follow such things.
If you dont call yourself Christian, then the Christian will perhaps judge you, tell you that you will go to hell or that you are not a true believer.
Whatever you choose, some will support you, some won't.
But what is really important is your relationship with Jesus and God. What others think is totally irrelevent.
Do what you think is best, stand up to what you believe in and know to be true and dont be afraid of opposition. Wherever you are you will encounter some. Unfortunatly there is no way around that. So better be in a position where you know your true feelings lies
Good luck and be well
