There is no problem in recognizing the four US Churchwomen (2 Maryknoll sisters, 1 Ursuline sister and 1 Lay Missioner).  It is clear that the same path to official recognition of martyrdom that applies to Blessed Oscar Romero and Fr. Stanley Rother applies to the four women.  Why aren't they recognized like Rother? The answer lies in the arcane and expensive procedures involved in the process of promoting the cause of holy people at the Vatican (reportedly the average cost to promote a cause for beatification and sainthood is over $250,000).  The Oklahoma Archdiocese has put its status and resources behind the cause of Fr. Rother.  No such entity has gotten behind the cause of the 4 North American women.
