Homily for the Thirty-third Sunday in Ordinary Time

What are you doing to build up the Kingdom of God? "The organic union in [the body of Christ] and the structure of the members are so compact that the member who fails to make his proper contribution to the development of the Church must be said to be useful neither to the Church nor to himself" (Vatican II, Decree on the Apostolate of the Laity, Apostolicam Actuositatem, 2)
