Even Jesus didn't expect everyone to love everyone: he was hoping for basic, non-violent tolerance. The word 'love' can be understood in many ways, including a vulgar, carnal sense that involves no affection or respect and a theological sense that doesn't, either. He may have meant something like: See that the other guy is just like you, and bear with his imperfections.
As a third-generation atheist I'm hardly an expert on Christianity. That said, nonetheless as a linguist I'm rather certain that he was using "love" in opposition to "hate." And remember that the New Testament was written in Greek, which has two words for love:
eros for passionate carnal love, and
agape for the love that we feel for our friends. Whenever you read a translation of a document, you have to settle for the likelihood that you're not getting exactly what the original says.
I'm sure Jesus did not expect us to be sexually attracted to our dogs or our favorite athletes or our president or even our priests--especially if we're both the same sex, although I'll go out on a limb and suggest that he would tell us to love gay people and therefore he would not object if a gay man feels sexual attraction for President Obama.
But back on topic, he specifically wanted us to love the sick and the poor and the downtrodden. That sure sounds like
agape to me.
Saint, have you ever thought of going to a religion/bible forum and asking all these questions instead of a science forum??
You should see the questions he asks on the Linguistics board.
Frankly I suspect that he wants the kind of answers he gets here, rather than the kind he'll get on a forum populated primarily by people who are so religious that they hang out on religious discussion boards.
The only time I stumbled into one of those places, a pastor was explaining to a mother why it would be okay to
lie to her children and assure them that their recently-deceased dog will indeed be waiting for them in heaven, even though proper Christian adults know that non-human animals have no souls and therefore no afterlife.
Will Rogers said:
If dogs don't go to Heaven, then when I die I want to go where they went.
Amen to that, Brother Will.
