You can deduct expenses as a work-related expense if you are already employed as a youth pastor, but the expense deduction is an itemized deduction and subject to the 2% floor, so you may not benefit. You can't deduct expenses as work-related if they are to change jobs or qualify for a new career.
Education expenses are eligible for credits if you are attending a school that is accredited by the US Dept of Education to participate in Federal student aid programs. If the school is accredited, they will issue a 1098-T. You can claim credits for tuition you paid plus required expenses for books and supplies.
