Question 54 — The Impediment of Consanguinity

We must next consider the impediment of consanguinity.

Under this head there are four points of inquiry:

(1) Whether consanguinity is rightly defined by some?

• (2) Whether it is fittingly distinguished by degrees and lines?
• (3) Whether certain degrees are by natural law an impediment to marriage?
• (4) Whether the impediment degrees can be fixed by the ordinance of the Church?
