Know this, brethren: do not creep out of the church before the dismissal prayer, for he who exits from the divine chant or converses or whispers has been seduced by demons, as the Divine Scriptures bear witness.
-- Saint Joseph of Volokolamsk
* Note: This quote reminds me of a story from a Catholic friend in Australia. It seems her parish priest was gone on a trip. The priest who was filling in was an all business Irish priest. It was in the heart of football season in Australia, and a good number of parishoners were slipping out of the parish before dismissal to get home in time to watch football, much to the Irish priests frustration. This had taken place on two straight Sunday's. The Irish priest told my friend he was going to put a stop to the early exits. The next Sunday, before the Mass began the priest said the following: "Before we begin Mass today, I want you all to keep one thing in mind. Judas was the only one to leave the Last Supper early." No one left early again.
