In the Gospel according to St. Matthew the kingdom of God consists in a right relationship to the true owner of the vineyard. The religious leaders have questioned Jesus' authority. Keep in mind that Jesus has arrived in Jerusalem. While in the temple, he is angered by the sight of numerous activities. Moneychangers have nice booths in which they carry out the business of changing world currencies into the money suitable for use in the temple.
Some merchants are there to sell animals and other paraphernalia.
Jesus goes through the temple overturning tables and disrupting all operations. Jesus narrates a series of parables in answer to this important question and he sets a trap for the religious leaders. The parable of the Wicked Tenants answers. My authority comes from the owner. The vineyard is the kingdom of God.
