Supposed Jesus Christ came back, what sects should Jesus Accept as true religion?

Because of thousands sects in christianity which sects is right to be chosen by jesus because some claimed he was not god some says his god.
As a muslim, we believe that Jesus is a mighty messenger of god and was a muslim. when he Jesus comes back he will be like us he is not messenger anymore. he's not going to teach trinity as christians believes but he will distruct the crosses and kill pigs, he will also kill anti christ ad-dajal.
