> right but the "only in communion with God" part seems less supported than the general need for love in a community/ fulfillment.
In the Christian tradition, love of neighbour is important:
> "Teacher, which commandment in the law is the greatest?" He [Jesus] said to him, "'You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.' This is the greatest and first commandment. And a second is like it: ‘You shall love your neighbor as yourself.’ On these two commandments hang all the law and the prophets."
And how does one love both God and neighbour at the same time? By loving one's neighbour one loves God as well:
> Then the righteous will answer him, saying, 'Lord, when did we see you hungry, and feed you; or thirsty, and give you a drink? When did we see you as a stranger, and take you in; or naked, and clothe you? When did we see you sick, or in prison, and come to you?'
> The King will answer them, 'Most certainly I tell you, because you did it to one of the least of these my brothers, you did it to me.'
Right, but you're taking as granted that people believe this, that they know about Christian theology, that it's true, that God exists, and so on?
That's a lot of leaps in logic. Knowing that people find community fulfilling can be observed in the people around you without any of that background, so surely it's the simpler concept?
