Feast of Thomas Becket, Archbishop of Canterbury, Martyr, 1170 It was the experience of the disciples who knew Jesus both before and after the Resurrection, and the conviction which they communicated to others, that laid the foundation of faith. This faith, once given, proved to be -- like the Person who gave rise to it -- essentially self-authenticating. And ever since, the Church has looked to the Cross, a symbol of weakness, as its unique source of power in preaching the Gospel, its authority both to teach and to preach has been of this kind. No amount of liaison between the Church and the source of any other authority, political or moral, must be allowed to obscure the simplicity -- and the mystery -- of the authority of Christ.
