On The Sacrament Of Matrimony., Canon III
ON THE SACRAMENT OF MATRIMONY.
CANON III.-If any one saith, that those degrees only of consanguinity and affinity, which are set down in Leviticus, can hinder matrimony from being contracted, and dissolve it when contracted; and that the Church cannot dispense in some of those degrees, or establish that others may hinder and dissolve it ; let him be anathema.
