Your take on the article is flawed.
Without getting into the agenda of the Mommy here--the consecrated WINE is also the "body, blood, soul, and divinity" of Christ--a point Mommy seems to wilfully miss.
Secondly, as the article should point out, the Church already has considered the needs of people with the girl's condition and has authorized low-gluten hosts.
The first point is far and away the most important one--there's a serious lack of either 1) catechesis on the parish's part or 2) belief in the doctrine on Mommy's part.
Take your choice--but it ain't rubrics, my man.
God doesn't care if the kid's wafer contained wheat or not. The insistence that He does, is a wonderful example of the sort of "rubricism" this article is talking about.
To see Jesus's take on such matters, look under "Pharisee" in the Gospels.
Hello. Remember Blessed Mother Teresa's teaching that the fruit of abortion is nuclear war. Pray for cities not to be erased. Thank you.
