Canon 21
A very long canon concerning the virgins and widows who marry after being consecrated to God. Both the man who marries this woman and the woman herself are excommunicated.
Et quicumque episcoporum aut presbyterorum uel diaconorum aut subdiaconorum eis communicare praesumpserit, usque ad synodum ab omnibus episcopis excommunis habeatur.
There follows presentation of particular cases and decrees of other synods.
