Do you not know that the original San Damiano Cross (Crusifix) was created around the year 1100 AD? All San Damiano Crosses since then are copies/representations of the original. By your logic, that would mean that there has been not "good pope" (your words) since 1100 AD... since this cross has existed for over 900 years. Is that what you believe?
If you look closely at the clouds passing by your house, it is possible to see animals, silly things, evil things and sexual things.... if you just look hard enough.
One can find evil and conspiracy around every corner, under every rock and within every person.... if he just looks hard enough and has made up his mind that he will find it.... even when it doesn't exist. I have come to the conclusion over the years that it is nearly pointless and futile to change someones mind when they are determined to find evil and conspiracy in everything.
It is also impossible to convince someone that we landed on the moon in 1969 if that person is determined to believe that the moon landing was a staged event created on a movie set.
It is also impossible to convince someone that humans created the pyramids of Egypt if that person is determined to believe that the pyramids were the work of aliens from outer space.
And finally, you wrote that the icon of Christ (in the San Damiano cross) had feet that "were unusually long as were the toes and resembled the feet of Satan". I've never seen a photograph of Satan's feet and I really doubt that one exists. Given that, how you know that Christ's feet and toes (in the cross) resembled those of Satan is completely beyond me. If you study a lot of religious icon artwork you will notice that physical human features are no necessarily exactly a average dimensions.
