Churches of Rome - Tituli

Only the tituli were allowed to distribute sacraments. The most important priest in a titulus was given the name of Cardinal. Pope Marcellus I (at the beginning of the 4th century) confirmed that the tituli were the only centres of administration in the Church. In 499 a.d., a synod held by Pope Symmachus listed all the presbyters participating, as well as the tituli who were present at that time.:

1. Titulus Aemilianae (Santi Quattro Coronati)
2. Titulus Anastasiae (Santa Anastasia)
3. Titulus SS Apostolorum (Santi Apostoli)

6. Titulus Clementis (San Clemente)
7. Titulus Crescentianae (San Sisto Vecchio)
