Humanity needed to "listen to the language of creation" to understand the intended roles of man and woman. He compared behaviour beyond traditional heterosexual relations as "a destruction of God's work.” The pope went on to say, “the Church should protect man from the destruction of himself. A sort of ecology of man is needed. The tropical forests do deserve our protection. But man, as a creature, does not deserve any less."
The Catholic Church teaches that while same sex attraction is not sinful, homosexual acts are. "homosexual acts are intrinsically disordered." They are contrary to the natural law. They close the sexual act to the gift of life. They do not proceed from a genuine affective and sexual complementarity. Under no circumstances can they be approved. (CCC 2357)
People suffering from a same sex attraction must be accepted with respect, compassion, and sensitivity. Every sign of unjust discrimination in their regard should be avoided. These persons are called to fulfill God’s will in their lives and, if they are Christians, to unite to the sacrifice of the Lord’s cross the difficulties they may encounter from their condition. (CCC 2358)
The pope also defended the Church's right to "speak of human nature as man and woman, and ask that this order of creation be respected."
It is great to hear a world leader speak so accurately about the current troubles humanity is facing with regard to human sexuality. Catholic pride at its best.
