Apostasy

Lately, the national news here in the U.S. has highlighted, unfortunately, some apostasy in the Body of Christ.  So as not to focus too much attention on the individual, I´ll speak without using names.  One person, unmarried, stated that although they consider themselves a ´Christian´, yet they have engaged any number of times in premarital sex.  They publicly criticized another Christian single person for NOT engaging in sex before marriage.  The former also publicly made obscene gestures, and publicly used profanity.  What´s the difference between the two?  Easy to point out!  One is trying to follow Christ according to Scripture, the other is in a pseudo-relationship, based on feeling, in CONTRADICTION of the Scripture.  The latter has fallen away from the faith.
