case 1: http://celtic-arts.org
case 2: https://celtic-arts.org
case 3: http://www.celtic-arts.org
case 4: https://www.celtic-arts.org
All four case produce the same results.

My next plan is to isolate the server on a locate network, de-active SSL to see if redirects stop or continue.
If redirects continue, I will do a complete re-install. Last option.
It would be nice if I could find the root cause that could possible help others out they may run into this same issue. Then again, this could an issue that no one else will ever see. This would be the best scenario.
