Artwork
Many of the comics at ReligiousCartoons were created at
stripcreator.com
with artwork from pseudonyms
"injokester",
"threereasons",
"dexx", and
"kaddar".
The composition and text, though, are the ideas of the people posting here.
It is easy to make comics at stripcreator.
Some comics are hand-drawn, for example those by Mostly True Comics
