I have a friend who is an elder at a mainline church, but his curiosity and doubt has led him to be more "open-minded" (his words) about his faith. So he refers to himself as a "follower of Christ" rather than a Christian. (And honestly, if the priest at his church knew his views on the origins of the Bible, he'd probably excommunicate my friend.)
But the true test is discipleship:
60 Therefore many of His disciples, when they heard
this, said, “This is a hard saying; who can understand it?”
61 When Jesus knew in Himself that His disciples complained about this, He said to them, “Does this offend you? 62
What then if you should see the Son of Man ascend where He was before? 63 It is the Spirit who gives life; the flesh profits nothing. The words that I speak to you are spirit, and
they are life. 64 But there are some of you who do not believe.” For Jesus knew from the beginning who they were who did not believe, and who would betray Him. 65 And He said, “Therefore I have said to you that no one can come to Me unless it has been granted to him by My Father.”
66 From that
time many of His disciples went back and walked with Him no more. 67 Then Jesus said to the twelve, “Do you also want to go away?”
68 But Simon Peter answered Him, “Lord, to whom shall we go? You have the words of eternal life. 69 Also we have come to believe and know that You are the Christ, the Son of the living God.” --
John 6:60-69
There's the real difference: spirit versus body. "Followers" do just that: they
follow Jesus without ever
believing He is the Christ, the Anointed One, the Messiah, the Son of the living God. It is expedient for them to say "I follow Jesus" to identify how they
act and not what they
believe in their hearts. When faced with the reality that the Bible and Christ do not give them the option to just
follow Him and not place their
faith on Him, the "followers" typically deny Him. "Christian" means "little Christ," and no "follower" will ever be close enough to the Savior to be mistaken for Him -- as they were at Antioch and other places since then.
"Follower of Christ" is less a politically correct term than one to allow someone who might normally consider himself a Christian to follow some of Christ's teachings without believing in the whole of the Bible. They are free to pick and choose what they want to follow, leaving out anything that doesn't suit their personal morality or their social norms. That's why seeker-sensitive churches appeal so much to such people, because the seeker churches talk very little about sin and a lot about finding fulfillment in being a good person and in helping others. Yes, we are indeed called upon to help others, but if we have not Love, we are as a clanging cymbal... And what kind of love does Jesus command? You all ought to know this one:
34 But when the Pharisees heard that He had silenced the Sadducees, they gathered together. 35 Then one of them, a lawyer, asked
Him a question, testing Him, and saying, 36 “Teacher, which
is the great commandment in the law?”
37 Jesus said to him, “
‘You shall love the LORD your God with all your heart, with all your soul, and with all your mind.’38 This is
the first and great commandment. 39 And
the second
is like it:
‘You shall love your neighbor as yourself.’ 40 On these two commandments hang all the Law and the Prophets.” --
Matthew 22:34-40
Note that the greatest commandment is to Love God. And to love God, we must strive to be holy, as He is holy. (Read
1 Corinthians 6 and
1 Peter 1:13-21) Perhaps, as with Jesus' earliest followers, that is a bit much to ask, and some may turn back. As for me and my house, we will serve the Lord. (See
Joshua 24, especially verse 14-15)
