-- Mt 19:16-22
To this first reply Jesus adds a second: "If you would be perfect, go, sell what you possess and give to the poor, and you will have treasure in heaven; and come, follow me." This reply does not do away with the first: following Jesus Christ involves keeping the Commandments. The Law has not been abolished, but rather man is invited to rediscover it in the person of his Master who is its perfect fulfillment. In the three synoptic Gospels, Jesus' call to the rich young man to follow him, in the obedience of a disciple and in the observance of the Commandments, is joined to the call to poverty and chastity. The evangelical counsels are inseparable from the Commandments.
