Excerpt from an article by Matthew Newsome:
“Sundays in Lent, Why It Doesn’t Really Make Sense”
Okay, that “40 days” thing doesn’t quite add up, because technically Lent ends on Holy Thursday, when the Easter Triduum begins (though our fasting continues up till the Vigil on Holy Saturday). So if you count the days from Ash Wednesday to Holy Thursday, it’s only 43 days. Then if you took out all the Sundays, you are left with 37 days. The reality is that the “40 days of Lent” is a close approximation.
Plus it is wrong to say that Sundays are “not really part of Lent.” They are. We call them “the First Sunday of Lent,” and so forth. They are most definitely part of Lent, which is why we include all sorts of Lenten practices on Sundays, such as the use of purple as a liturgical color, the absence of the Gloria and Alleluia, and so on.
Also, the notion of not continuing your Lenten fast on Sundays seems to be very new. Granted, I have not researched this idea thoroughly, but in the past when the Church’s Lenten practices involved eating a nearly Vegan diet for the entirety of Lent, I can recall reading nothing to indicate that Sundays were considered “days off.”
Moreover, none of the older Catholics I speak to remember Sundays being considered this way in the past. Even when I went through RCIA myself in the year 2000 nothing was ever mentioned about Sundays being an exception to our Lenten practices.
This idea seems to be a rather new phenomenon.
My two cents agreeing with above article excerpt is;
This is Part of the routine of a compromising Church and a strategy of the enemy attacking the Church from within to weaken Catholics in Spiritual warfare.
