Words Not Found in Scripture – Deacon
Lew Ayotte posted an excellent study on the word "deacon". Given what a fixture the office of deacon is in much of the church, this is an excellent study of what it does (and does not) say it Scripture. I will leave it to the Greek scholars to decide if the interpretation is correct but it certainly exhibits a great deal of study. You should check it out, especially if you are versed in Greek.
