Good to know there is grace within Catholic church theology.
I would have given the girl communion, unless there were theological grounds for denying it. I’m on the side of grace of these issues, because people are imperfect.
This girl has no doubt been receiving the Most Holy Sacrament of the Altar on the tongue and while healing since her very First Communion.
With the courage she showed in not budging despite the bishop misbehaving like a small child, she will no doubt never, ever in her life allow her unconsecrated hands to touch the Body, Blood, Soul and Divinity of our Lord, Jesus Christ, leaving it only to an ordained priest distributing it directly on her tongue while she is kneeling, the most reverent posture possible.
