Sermon Image Not Centered

Looks like your theme is adding a (right) sidebar. Probably the easiest way is to hide the sidebar in CSS. Go to ‘Appearance > Customize > Additional CSS’ and add this:

.wpfc_sermon-template-default .sidebar-primary {display:none;}
.wpfc_sermon-template-default.full-width-content .content {margin-left:auto !important;}

That should center the content and remove the sidebar.

Thanks for your help! That centered the whole block and removed the sidebar.

How do I center the sermon image above the title of the sermon?

Thanks again for your help!

Ah, forgot about this guy:
.wpfc-sermon-single-image{text-align:center}
