The teachings of Jesus were not popular - He was crucified for them.
The posts on this thread certainly confirm that Pope Francis current proclamation is very popular, but is it God's will or the will of the people? The Christian bible warns us that the ways of the world are not God's ways.
But if God made the world, then the way the world behaves must be God's way.
The RC view of sex and sexual behaviour is essentially developed from the writings of a 13th century monk named Thomas Acquinas, whose inspirational sources were from Aristotelian natural philosophy not the bible. The RC view of sexual behaviour has been that the sole purpose of coitus is reproduction (encouraged to ensure that the pews would always be full) and that coitus for any other purpose is sinful. After all, if you look at any other type of creature, sexual activity is followed by pregnancy.
The way the human world behaves is different from the animal world. Coitus, in fact sexual behaviour generally, serves a totally different purpose: it provides a mutual reward to the participants and encourages the maintenance of a close, affective relationship. From a purely procreational point of view, what purpose does sex serve for a post-menopausal woman?
Unlike any other animal on Earth, homo sapiens takes the best part of 20 years to reach full adulthood. The purpose of sexual behaviour can also be to ensure that human offspring are given the opportunity to develop in a relatively protective environment so that they stand a good chance of reaching adulthood. This, surely, is more likely to have been "God's way" than "be fruitful and multiply".
And as for non-reproductive, same sex, relationships? Mutual reward brings security, safety and fulfilment. Two people of the same sex may also have parental responsibilities. Their relationship affords stability for children in just the same way as a heterosexual relationship does. For a "loving God" this seems to be much more likely to me.
And how do we know that Jesus wasn't gay, anyway?
