Letter 14 of Pope Gelasius, written on 11 March 494, was addressed to the bishops of Lucania and Bruttium (i.e. nowadays Calabria) and Sicily. They were under Gelasius' direct metropolitan jurisdiction. The long letter is a "decretal", and mainly contains various norms regulating the rights and obligations of clergy.
Only the title of the chapter is given here. Its first sentence is explained in the full text of the chapter; it says that even if there was recently a relaxation of some rules, because of pressing necessities, the ancient practice must be restored.
The next chapter of the letter (Chapter 25) prohibits the consecration of a new church or place of cult without the consent of the Apostolic See.
