nounRoman Catholic Church
A papal decree of 1907 clarifying canon law with regard to marriage, which declared that no marriage between two Catholics or a Catholic and a non-Catholic is valid unless solemnized by a Roman Catholic priest.
The decree was designed specifically to clarify the contents of the 1563 decree Tametsi.
Early 20th century; earliest use found in The Tablet. From post-classical Latin ne temere ‘lest rashly’, the opening words of the decree from classical Latin nē + temere rashly.
