15. It is also a great blessing that the Church has limited, so far as is needful, the power of fathers of families, so that sons and daughters, wishing to marry, are not in any way deprived of their rightful freedom; (²⁶) that, for the purpose of spreading more widely the supernatural love of husbands and wives, she has decreed marriages within certain degrees of consanguinity or affinity to be null and void;(²⁷) that she has taken the greatest pains to safeguard marriage, as much as is possible, from error and violence and deceit; (²⁸) that she has always wished to preserve the holy chasteness of the marriage bed, the security of persons,(²⁹) the honor of husband and wife,(³⁰) and the sanctity of religion.(³¹) Lastly, with such foresight of legislation has the Church guarded its divine institution that no one who thinks rightfully of these matters can fail to see how, with regard to marriage, she is the best guardian and defender of the human race; and how, withal, her wisdom has come forth victorious from the lapse of years, from the assaults of men, and from the countless changes of public events.
