I just finished celebrating the daily Sung Mass with all the students and faculty, where we heard this Gospel:
While the people pressed upon him to hear the word of God, he was standing by the lake of Gennesaret. And he saw two boats by the lake; but the fishermen had gone out of them and were washing their nets. Getting into one of the boats, which was Simon's, he asked him to put out a little from the land. And he sat down and taught the people from the boat. And when he had ceased speaking, he said to Simon, "Put out into the deep and let down your nets for a catch." And Simon answered, "Master, we toiled all night and took nothing! But at your word I will let down the nets." And when they had done this, they enclosed a great shoal of fish; and as their nets were breaking, they beckoned to their partners in the other boat to come and help them. And they came and filled both the boats, so that they began to sink. But when Simon Peter saw it, he fell down at Jesus' knees, saying, "Depart from me, for I am a sinful man, O Lord." For he was astonished, and all that were with him, at the catch of fish which they had taken; and so also were James and John, sons of Zebedee, who were partners with Simon. And Jesus said to Simon, "Do not be afraid; henceforth you will be catching men." And when they had brought their boats to land, they left everything and followed him.
Every year, when this Gospel is read at the school Mass, I talk to them about fishing nets. After describing how the apostles used their nets to catch fish, I move on to our Lord's promise to St. Peter, "...henceforth you will be catching men." Jesus would give the apostles a new net - the net which is the Gospel - and with this net they would gather people and bring them as a catch, to the Table of the Lord. It gives me an opportunity to remind them that we ourselves have been caught up in this Gospel net, and then I point out to them the symbolism we have on the ceiling of the nave: the blue color (reminding us of heaven) with a gold net superimposed upon it (reminding us of this Gospel which was read today).
