It depends. If the church is an accredited school, you can deduct the tuition as your education expenses. Otherwise, you cannot.
If you took the courses to prepare your for a new skill/work, they are not deductible either. However, if you work and the courses are for your existing trade/skill, they are deducted as your job-related expenses if you are an employee or as your regular "business" expenses if you are self-employment. If none of the above applies, you cannot deduct the courses, they are considered personal and are not deductible at this point.
