>Two verifiable postmortem miracles
>Note: Canonization (sainthood) requires two miracles, whereas beatification (blessed) requires only one.
>Evidence of having led an exemplary life of goodness and virtue worthy of imitation, having died a heroic death (martyrdom), or having undergone a major conversion of heart where a previous immoral life is abandoned and replaced by one of outstanding holiness
If I recall the church is actually nonchalant about miracles performed by living Catholics since it it treated more like a "Obviously we you can perform miracles the Lord told us we could so stop making a big deal about it." Postmortem miracles are different though because it shows the Grace of the Lord was so strong in the person that their body literally radiates it meaning they are assuredly in heaven. Or something like that.
