There is just as much practical knowledge in the field of theology as there is psychology, sociology and many of the other soft sciences.
No there isn't. There is almost no knowledge in theology at all, except for knowledge of some arcane scriptures.
theology only has the human experience to study and as such, is probably dead on with how the world behaves.
There is not the slightest evidence for that claim. Moreover, the study of human experience is part of psychology.
Science and religion do not have to be opposed to each other. They can coexist quite happily.
Only in the mind of hypocrites, namely people who apply completely different standards of adequacy, consistency and correctness to religion and science without being able to explain why they would be justified to do so.
The only conflict comes is when either goes beyond it's theoretical framework and tries to apply it to the other.
Religion really has no 'theoretical framework' worth speaking of. It's a bunch of old stories with a lot of bullshit in them, plus some mildly interesting and arcane cultural heritage and rites.
