Unless you are referring to actually being in love with this person, the correct word would probably be admiration, not love or attraction. ad·mi·ra·tion- 1. A feeling of pleasure, wonder, and approval. 2. An object of wonder and esteem; a marvel

Definitely NOT attraction. Attraction is generally used only in the sexual sense. You could say love but it's unlikely. Admiration or respect are likely the best words to use in that context.

Attraction is not necessarily sexual. A person could be attracted to other people with strong faiths, and another person could be attracted to people who appreciate their devotion. This type of attraction is of an emotional, personal nature, rather than a physical or sexual nature. I think many relationships are also founded on this type of attraction and personal compatibility. Love is difficult because it's more complicated than liking a single trait in a person. Attraction is a better word to use when discussion a certain attribute.
