A more thorough explanation:

nuptiae secundae

In the context of Ecclesiastical law, nuptiae secundae refers to a second or subsequent marriage.

Example 1: After her first husband passed away, Maria entered into nuptiae secundae with a widower from her church.

Example 2: The priest refused to officiate at the nuptiae secundae of the couple because it was against the canon law.

The term nuptiae secundae refers to a second or subsequent marriage. In the examples provided, Maria entered into a second marriage after her first husband passed away, while the couple in the second example were denied a church wedding because it was their second marriage. In Ecclesiastical law, second or subsequent marriages were not encouraged, and priests would often refuse to officiate at those ceremonies.
