Again, it is important to remember that the rule itself concerned priests mainly and that, undoubtedly, they were bound by it, and we see from the English canons re-enacting it the severe penalties to which they became liable in the ecclesiastical courts in England for any breach of it. Therefore, the disregard of it by the civil courts would have caused a perpetual conflict between these two tribunals even where the former was only exercising the jurisdiction which rightfully belonged to it, besides the fact that it would have so sharply conflicted with the religion practised by the nation.
The rule in question primarily affected priests and they were obligated to adhere to it. The English canons demonstrate the severe punishments imposed on them for violating this rule by ecclesiastical courts. Therefore, ignoring it by civil courts would have led to ongoing conflict between these two judicial bodies, even when the former exercised its rightful jurisdiction. Additionally, such a conflict would have been incompatible with the religion practiced by the nation.
