Today one has to spell out who is a CHRISTian and who is not.
The ones who are followers of CHRIST and His word are CHRISTians.
All the rest are people who identify themselves as Christians.
Jesus said: "And he answered and said unto them, Have ye not read that he which made them at the beginning made them male and female, And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh? Wherefore, they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder." -from THE BIBLE: Matthew 19:4-6
Have you followed Mark 16:16 to the letter? If you have not been baptized, you arent saved. Pure and simple: "He who believes and is baptized shall be saved, but he who does not shall be damned".
