Saint Mark did not ask to become a saint, in the bible he is called a deciple and a apostle. We are all desiples if we believe in Jesus and follow in this matter we are saints according to the washing of Catholics call him a saint in a way of high respect.

He was officially recognized as a Saint in the earliest days of the Christian Community.
