Today’s Reading: Matthew 5:13-20

13 “You are the salt of the earth; but if salt has lost its taste, how shall its saltiness be restored? It is no longer good for anything except to be thrown out and trodden under foot by men.

14 “You are the light of the world. A city set on a hill cannot be hidden. 15 Nor do men light a lamp and put it under a bushel, but on a stand, and it gives light to all in the house. 16 Let your light so shine before men, that they may see your good works and give glory to your Father who is in heaven.

17 “Do not think that I have come to abolish the law and the prophets; I have come not to abolish them but to fulfil them. 18 For truly, I say to you, till heaven and earth pass away, not an iota, not a dot, will pass from the law until all is accomplished. 19 Whoever then relaxes one of the least of these commandments and teaches men so, shall be called least in the kingdom of heaven; but he who does them and teaches them shall be called great in the kingdom of heaven. 20 For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.

Today’s Commentary:

Two illustrations show that disciples must be true to their calling lest they render themselves useless for the kingdom. Being the salt of the earth, they are to season and preserve the world with peace (Mk 9:50) and gracious speech (Col 4:5). Being the light of the world, they are to bear witness to Jesus and his message (Jn 1:9; 8:12).

Both images have links with the OT. Salt is associated with the covenant of priesthood made with Aaron and his descendants (Num 18:19) as well as the covenant of kingship made with David and his descendants (2 Chron 13:5). Light is associated with the OT vocation of Israel to make the truth and justice of God shine out to all nations (Is 42:6; 49:6).
