“People talk about beautiful relationships between two persons of the same sex. What is the best of that sort as compared with the friendship of man and wife where the best impulses and highest ideals of both are the same? There is no place for comparison between the two friendships; the one is earthly, the other divine.”

“When the two people who thus discover that they are on the same secret road are of different sexes, the friendship which arises between them will very easily pass – may pass in the first half hour – into erotic love. Indeed, unless they are physically repulsive to each other or unless one or both already loves elsewhere, it is almost certain to do so sooner or later. And conversely, erotic love may lead to Friendship between the lovers. But this, so far from obliterating the distinction between the two loves, puts it in a clearer light. If one who was first, in the deep and full sense, your Friend, is then gradually or suddenly revealed as also your lover you will certainly not want to share the Beloved’s erotic love with any third. But you will have no jealousy at all about sharing the Friendship. Nothing so enriches an erotic love as the discovery that the Beloved can deeply, truly and spontaneously enter into Friendship with the Friends you already had; to feel that not only are we two united by erotic love but we three or four or five are all travelers on the same quest, have all a common vision.”

“Married people should be best friends; no relationship on earth needs friendship as much as marriage...Friendship in a marriage is so important. It blows away the chaff and takes the kernel, rejoices in the uniqueness of the other, listens patiently, gives generously, forgives freely. Friendship will motivate one to cross the room one day and say 'I'm sorry. I didn't mean that.' it will not pretend perfection nor demand it. It will not insist that both respond exactly the same in every thought and feeling, but it will bring to the union honesty, integrity. There will be repentance and forgiveness in every marriage--every good marriage--and respect and trust.”

“Each relationship between two persons is absolutely unique. That is why you cannot love two people the same. It simply is not possible. You love each person differently because of who they are and the uniqueness that they draw out of you.”

“Friendship is a deep oneness that develops when two people, speaking the truth in love to one another, journey together to the same horizon.”

“There are no faster or firmer friendships than those formed between people who love the same books.”
