“The disciple is not above his master: but every one that is perfect shall be as his master” (Luke 6:40).
It is Ash Wednesday. It is the genesis of the Lenten season. In preparation for Easter the Church has historically found this to be an opportune time for confession of sin and imitation of Christ. Such practices are good and lawful; Spirit-led, that.
It is, therefore, a time for disciples, the pupils, the followers and adherents to the way of Christ, to confess sins and become as their master.
