There is a very simple theme to this Sunday’s readings: it is the principle of authority in the community of the Church: we are introduced to the idea that God gives authority to someone in the first reading, where Shebna is dismissed by God and replaced. This is a prelude to the Gospel story of Peter being given authority: not because he is powerful or wise in the world’s sense, but because he was able to profess his faith in the one sent by the Father. This is the principle of all authority in the Church: it is to spring only from God and our faith in God, professed by our way of life and rooted only in Christ, for ‘to him all authority, in heaven and on earth, has been given.’
