“We know that in times of momentous change the homosexual phenomenon grew, but in this period it is the first time that the legal problem of assimilating it to marriage has arisen, and this I consider an anti-value and an anthropological regression,” says the Pope. “I say this because it transcends the religious issue, it is anthropological.” “If there is a union of a private nature, there is neither a third party nor is society affected,” he writes. “Now, if the union is given the category of marriage and they are given adoption rights, there could be children affected.” “Every person needs a male father and a female mother that can help them shape their identity,” says Pope Francis.

I would not agree with the statement that “if the union is a private nature, society is not affected”, as the Pope states. Sin affects society. But he is absolutely right when he says that children do indeed need a mother and a father…because neither mother or father is an arbitrary relationship to a child. It has meaning and it is necessary.
