"From the altar, I could see perfectly at the bottom of the choir Sister Lucia, who, later on, also distinguished herself at the moment of distributing Holy Communion.?
Some confusion here. Is the person telling the story saying "Sr Lucia" was herself distributing Holy Communion like a Eucharistic Minister?
How else would she distinguish herself based on this statement? Lost in translation? Sounds bizarre.
(BTW you'd have to be blind not to see that the two Sr Lucy's are not the same person.)
