Obviously, the word membership does not occur in the Bible, but this does
not mean it is an unscriptural word. There are many theological words that describe
Bible truths that do not occur in the Bible, such as trinity. For
example, the letterhead is biblical for two reasons. First, because we observed
in the New Testament that church pastors always knew who their sheep were in fact.
For example, Luke tells us the number of sheep. Three thousand people
were added, says at the end of chapter two. Then he says that
more were added until there were five thousand men. So they were counting.
But the other reason is the teaching of the New Testament. Many of the
Bible’ s commands assume that there is a definite membership. For example,
sheep must obey their shepherds and shepherds have a responsibility towards their sheep. Peter
also tells the elders to feed the green that is among you taking care of
it and then adds not as having, Lordship, on those in your care.
But this is only possible if the elder knows who is in his care.
Another passage would be matte eighteen. It describes the process of ecclesiastical discipline.
He says if anyone in the Church sins against you, you should go
and call her repentance. If he doesn' t regret it, you have
two or three witnesses. If you still don' t repent, you tell
the whole congregation. Say if you still don' t get him out of
the congress. In other words, there is a clear line between those who
do and those who do not belong to the church membership.
