Did Roman Catholic Church law ever condone (the contemporary practice of) incest?

I may not be asking the right question, but I'm trying to figure out the context behind a quote from [an Arthur Pink sermon](http://www.pbministries.org/books/pink/Sermon/sermon_06.htm) : > herein we may see the blasphemous impiety of the popes of Rome, who in the canons have dared to dispense with some of the laws of consanguinity in [Leviticus 18](https://www.biblegateway.com/passage/?search=leviticus+18&version=NABRE) What's he talking about? A little vocabulary help from Wikipedia: > Consanguinity ("blood relation", from the Latin consanguinitas) is the property of being from the same kinship as another person. In that aspect, consanguinity is the quality of being descended from the same ancestor as another person
