Mark 1:14-20 (the same Gospel of two Mondays ago) is a record of the beginning of the Lord's choice of the twelve Apostles whom he ordains to be "fishers of men," a title and dignity he gives only to his Apostles. That title is significant regarding the essential difference between clergy and laity.
Only certain men are ordained by Christ as "fishers of men!"
