=== Liturgical codification ===
Sixtus I instituted several Catholic liturgical and administrative traditions. According to the ''[[Liber Pontificalis]]'' (ed. Duchesne, I.128), he passed the following three ordinances:
* that none but sacred ministers are allowed to touch the sacred vessels;
* that bishops who have been summoned to the Holy See shall, upon their return, not be received by their diocese except on presenting Apostolic letters;
* that after the [[Preface (liturgy)|Preface]] in the [[Mass (liturgy)|Mass]], the priest shall recite the ''[[Sanctus]]'' with the people.<ref name="ce" />
