New Testament terms for the people of God I commonly hear Christians refer to themselves either with that terms, "Christians," or as "believers". However, when I read the New Testament, particularly Paul's epistles, these do not strike me as the foremost terms that are used to refer to the people of God. In the New Testament, and particularly from the Acts of the Apostles onwards, what terms are used to refer to Christians, and with what frequency? Which are most prominent? I am particularly interested in the relative frequency of "Christian," "believer," and "saint," but an inclusion of other titles would also be helpful.
Interesting question. From what I can tell 'brother' if the most common term, followed by saints and believers, far behind in second place. Christian is what outsiders called the believer so it is last.

Here are the hits based on the greek words;

Χριστιανός Christiania; Christian 3 

πιστός pistos -believers,faithful 53

ἅγιος hagios - saints 61

ἀδελφός adelphos -brethren 226
(brother 113)

My take on these is we are to feel bound to one another as a close knit family. However we need not become legalistic about it, for in our Culture I think we have revised the meaning of Christian to hold that same proud bond we share with each other.

Right brothers and sisters?
