Patristic Wisdom: Looking to the Eighteenth Sunday after Pentecost

Then they departed from there and passed through Galilee, and He did not want anyone to know it. For He taught His disciples and said to them, “The Son of Man is being betrayed into the hands of men, and they will kill Him. And after He is killed, He will rise the third day.” But they did not understand this saying, and were afraid to ask Him. Then He came to Capernaum. And when He was in the house He asked them, “What was it you disputed among yourselves on the road?” But they kept silent, for on the road they had disputed among themselves who would be the greatest. And He sat down, called the twelve, and said to them, “If anyone desires to be first, he shall be last of all and servant of all.” Then He took a little child and set him in the midst of them. And when He had taken him in His arms, He said to them, “Whoever receives one of these little children in My name receives Me; and whoever receives Me, receives not Me but Him who sent Me.” (Mark 9:30–37)

Let vanity not be known among you; rather, let simplicity and harmony and a guileless attitude weld the group together. Let each persuade himself that he is not only inferior to the brother at his side, but to all men. If he knows this, he will truly be a disciple of Christ. For, as the Savior says: “Everyone who exalts himself shall be humbled and he who humbles himself shall be exalted.” And again: “If any man wishes to be first among you, he will be last of all”; and the servant of all: “for the Son of man has not come to be served but to serve and to give his life as a ransom for many.” And the apostle: “For we preach not ourselves, but Jesus Christ as Lord; and ourselves merely as your servants in Jesus.” Knowing, then, the fruits of humility and the penalty of conceit, imitate the Master by loving one another and do not shrink from death or any other punishment for the good of each other. But the way which God entered upon for you, do you enter upon for Him, proceeding with one body and one soul to the invitation from above, loving God and each other. For love and fear of the Lord are the first fulfillment of the law.
