Nope. :nope:
Ashes aren’t about
fasting, they’re about
repentance. (After all, if they were about fasting, then we’d go for ashes again on Good Friday, right?)
So, the passage you quoted doesn’t apply here. (In fact, non-Catholic Christians sometimes attempt to use this exact passage to tell Catholics that we’re acting against Christ’s wishes. It’s a misunderstanding of the passage.)
Rather, the appropriate passage to quote comes from Matthew 11:
Here, Jesus speaks approvingly of repenting “in sackcloth and ashes.”
So, far from being an example of Catholics doing something that Jesus forbade, it’s an example of doing things precisely the way Jesus recommends…
