Try the easy way first. Just an opinion but for the best appearance, the vertical lines should be equadistance from the center of the lens and on the same distance plane. This shot is off to the side so the result will be skewed. Your right side bends left and the left side bends right. It's a result of parallax. To improve the shot I believe you need to be taking your photo from the dead center of the front doors and shooting exactly perpendicular to the church. Try it and compare. At that range with a wide lens you will still get some pincushion distortion but it will be less noticeable if both sides are the same. Other than that you'll need the tilt-shift capability for architectural photography. Before the new tilt-shift lenses we used bellows. A very short one just long enough to tilt the lens without getting much of the macro effect. If memory serves me right we (junior high) built it.
