Fr. Scott Gunn has an excellent post over at his place. It is making the rounds on the blogs today.

He strikes at the core of the Church. We do good works by virtue of the faith that lives in us. Good works are no substitute for for genuine faith.

Ultimately, faith is trust in God, and the Church is the community united in that trust. We act out of our trust that God cares for us and this world.

Fr. Gunn puts it well.
