William Brodie, respectable city councillor by day and burglar by night in 18th century Edinburgh, was the historical figure who inspired R. L. Stevenson to create Jekyll and Hyde. Although 'Deacon' was his title rather than his given name, he is so well remembered only as "Deacon Brodie" that many people nowadays believe it to have been his actual name.
The name annoys me big time. It's a religion-related profession, and I hate Christianity and all religions with a flaming passion. It doesn't sound particularly exciting anyway.
And what if Deacon turns out to be atheist or becomes a Satanist? This name just does not work for me; I don't trust organized religion and any name that sounds like only a die-hard religious zealot picked it turns me off.
The word comes originally from the Greek word diakonos, which means minister or servant. This can be seen in A Greek-English Lexicon of the New Testament and Other Early Christian Literature fourth edition edited by Danker.
Wow, people. Just wow. Why should the origin of the name make you hate it? And you idiots who hate religious people need to try to tolerate people who have different beliefs than you. I am not religious, but I still respect people who are. I respect them because they are different, and our differences are what make us interesting. Narrow-minded people like you guys are the reason our world is falling apart. Just think of Hitler. He hated people who were Jewish because they were different than he was. The KKK hates people who are black because they are different. See where I am going with this? Hate is the undoing of all mankind. I am not a pacifist, I am not a hippie, but I still think that hate and fighting aren't the answer. I used to hate people who were different, too. I used to dislike Jewish people because the one Jewish person I knew was mean to me, and that made me think all of them were like that. But then I met a girl who was Jewish, and now we are good friends. I respect Jewish people now. I may not agree with everything everyone believes in, but I try to tolerate them.
Now, back to the name Deacon. I think the name Deacon is a fine name. A famous bearer is the bassist John Deacon of Queen. I would honestly name my son this. I think it is a very nice name, and I like the nickname Deaky.
