How do you make the jump from legislating discriminatory behavior and belief? Not you, they. How can legislators make that jump?
Because the Catholic Church says this about marriage:
1601 "The matrimonial covenant,
by which a man and a woman establish between themselves a partnership of the whole of life, is by its nature ordered toward the good of the spouses and the procreation and education of offspring; this covenant between baptized persons has been raised by Christ the Lord to the dignity of a sacrament."
1603 "The intimate community of life and love which constitutes the married state has been established by the Creator and endowed by him with its own proper laws. . . .
God himself is the author of marriage."87
The vocation to marriage is written in the very nature of man and woman as they came from the hand of the Creator. Marriage is not a purely human institution despite the many variations it may have undergone through the centuries in different cultures, social structures, and spiritual attitudes. These differences should not cause us to forget its common and permanent characteristics. Although the dignity of this institution is not transparent everywhere with the same clarity,88 some sense of the greatness of the matrimonial union exists in all cultures. "The well-being of the individual person and of both human and Christian society is closely bound up with the healthy state of conjugal and family life."
1625 The parties to a marriage covenant
are a baptized man and woman, free to contract marriage, who freely express their consent; "to be free" means:
- not being under constraint;
- not impeded by any natural or ecclesiastical law.
And it says a lot more on the topic that HR5 would consider as “discriminatory.” The belief is a de facto act, defined by the belief (the Truth) itself.
