Wow.... you are right. I just went to a Dictionary; but you know how biased that can be. < /sarcasm>
Here's a hint click here.
As you apparently do not read the links, I'll copy it here for you.
1.) The study of the nature of God and religious truth; rational inquiry into religious questions.
2.)A system or school of opinions concerning God and religious questions: Protestant theology; Jewish theology.
3.)A course of specialized religious study usually at a college or seminary.
The law in Washington bans public funds from the study of theology. One degree in theology could include studies in all of the above specialised branches of theology. The state university system in Washingtom has undergraduate and post graduate degrees in religion studying the same theologies. Presumably the public is subsidising that.
Theology is the science of religion, or God, if you prefer, not a sect nor a branch which is what you seem to be fixated on.
