Depends on how your income is reported to you. If the entire amount is attributed to you by a tax document or your bank account then deduct the commission as an expense on Sch C. If your income reflects the commission just report the net income.
Both are acceptable.
There is nothing special you can claim because the gallery is also a church. Nothing counts as a donation. And if you did donate a painting, you can only take a deduction for the costs of materials, unless you report the donation as a sale with taxable income.
(The church might have Unrelated Taxable Business income -- UBTI -- and they could be in serious trouble if they gave receipts indicating that any part of the purchase was tax deductible to the buyer -- but that is their problem, not yours.)
