The Franciscans — who used to be wonderful before they went left — taught us to keep those fingers pointed upward as we approached the Communion rail. They also drilled into us the importance of showing proper reverence for the Blessed Sacrament in our deportment going to and returning from Communion and in our manner of dress.
When I see the girls in their immodest dress, I would give anything to see Sr. Leonita grab them and take them aside.
