In the past few Sunday gospels, Jesus has gone to great care to admonish and instruct the Pharisees. And then, clearly, He was certain that His lessons were recorded in the Word, because they are as timely today as they were when He walked the earth.
In today's gospel, Jesus said: “You shall love the Lord your God with all your heart, and with allyour soul, and with all your mind. This is the great and first commandment. And a second is like it, You shall love your neighbor as yourself.
-- Matthew 22:37-39
