"But in your hearts set apart Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect, keeping a clear conscience, so that those who speak maliciously against your good behavior in Christ may be ashamed of their slander." ~ 1 Peter 3:15-16
Found an interesting article that has been excerpted from Frank Viola's book named, "Pagan Christianity: The Origins of Our Modern Church Practices". The article titled "The Pastor: Where Did He Come From?" and you can read by clicking on the title. Here's a small introduction to the article for your interest:

It is a universal tendency in the Christian religion, as in many other religions, to give a theological interpretation to institutions which have developed gradually through a period of time for the sake of practical usefulness, and then read that interpretation back into the earliest periods and infancy of these institutions, attaching them to an age when in fact nobody imagined that they had such a meaning. -Richard Hanson

The Pastor. He is the fundamental figure of the Protestant faith. He is the chief, cook, and bottle-washer of today’s Christianity. So prevailing is the Pastor in the minds of most Christians that he is better known, more highly praised, and more heavily relied upon than Jesus Christ Himself!

Be warned that Frank Viola's books are so called "controversial" among the mainstream and it requires an open mind to rethink modern Christianity. Whichever side of the camp you might take, be sure not to be overly critical and to display Christ's love at all times. May you be blessed.
