Hahaha...a kindergarten graduation certificate has more value than canonization.
My post did not deserve your belittling remark. You asked whether the Church said all popes are in Heaven. My response explained that it does not. I answered your question.
But perhaps that wasn’t the answer you were looking for. I’m guessing from your belittling response to me that you would much prefer if my response agreed with your incorrect assumption that the Church teaches that all popes are in Heaven.
