John,
The word 'Christian(s)' [
Christianos] only appears in three places in the NT; Acts 11:26; 26:28; 1Pet 4:16. It is most always understood to mean "follower of Christ".
A 'follower' must be an active agent, no? who is moved along by the indwelling Spirit (Phil 2:12,13).
Can you explain what is bothering you with this phrase, "follower of Christ", a little more than you have?

What could also be true is that there is a 'new fad' as you put it coming on the scene that has a different understanding of what it means to be a Christian.
