There's no single answer to how many credits are required for a bachelor's degree in theology. The number of credits needed varies significantly depending on the specific university or seminary offering the degree, and even within a single institution, different concentrations or tracks might have slightly different credit requirements.
Generally, expect a Bachelor of Theology (BTh) or a Bachelor of Arts (BA) in Theology to require between 120 and 130 semester credits, or the equivalent in quarter credits. However, it's crucial to check the specific requirements on the website of the institution you're interested in.
