No. We must always remember that every person has an inherent dignity because he or she is created in the image and likeness of God, and that God loves every person as a unique individual. Like all other human beings, our homosexual brothers and sisters are beloved children of God. As a result, the Catholic Church affirms that they “must be accepted with respect, compassion and sensitivity. Every sign of unjust discrimination in this regard should be avoided” [Catechism of the Catholic Church no. 2358].
Thus the teachings of the Church make it clear that the fundamental human rights of homosexual persons must be defended, and that all of us must strive to eliminate any forms of injustice, oppression, or violence against homosexual persons.
But it is not “unjust discrimination” to treat different things differently. Same-sex unions are not, in fact, the same thing as the union of one man and one woman in marriage. One type of union may ever generate children, the other may never; one type of union respects and expresses the inherent complementarity of man and woman; the other does not. Therefore, treating one type of union as “marriage,” and the other not, is not only permitted, but required. Indeed, it is treating this differentiation as bigotry that constitutes an injustice.
