Key word being mother theresa TYPE. I think this was used by RD in a generic altruistic sense, not literally saying you'd have to be up to mother theresa spec to be considered in this stat.
Well, okay. So how many "Mother Teresa types" have there been in the last 50 years? (I limit myself to that time scale because the period covered by the John Jay study is only the last few decades.)
And just what is a "Mother Teresa type?" Well, I'll use the fact that Mother Teresa was Beatified. So, we're asking how many Blesseds have there been who lived during the last 50 years.
There have been 772 Blesseds in the entire 2000-year history of the church:

(Go to the bottom of the page - Maria Alfonsina Danil Ghattas was the 772nd person Beatifieid.)
And that number includes vast "Beatification inflation" in recent years. For example, in one fell swoop in 2007, 498 Spaniards who died during the Spanish Civil war were Beatified as martyrs. And late last year, 188 Nagasakians who died when the second A-bomb was dropped were Beatified as martyrs. That's 686 in just two years (but all those martyrs died before the John Jay study period began).
I've decided I'm going to exclude simple martyrs, and restrict the "Mother Teresa types" only to Blesseds who serve others without sexually preying on them. And there are fewer than 200 of them in the history of the church.
So, if there have been 200 non-martyr Blesseds in the 2000-year history of the church, we can expect 5 non-martyr Blesseds in the 50-year study period. That makes the ratio of pedophile priests to "Mother Teresa types" 1000 to 1.
Sorry about that.
