That's certainly A miracle, but it is in no way expected or required as a condition of canonization.
Are you speaking of the autopsy? My belief - in times like these - I do not think that is going to be an issue. God is FULLY aware of the need to do this. I believe it was through His Will that this was so swiftly carried out. How else to medically (and by this world's standards) prove that she was more than Michael claimed?
Had he refused, he would have truly looked guilty - and poor baby didn't want that - but by this autopsy(I am sure Michael thought about this and was counseled by George)- some of the truth will finally come out, then the Schindlers can proceed - as we can - with doing what needs to be done - seeking Justice.
We all just need to be prepared for the lies Schiavo and Felos are going to tell, Greer is going to back up - when the results come in . I am sure Michael is preparing a story for every injury she ever sustained. JK
