Jesus answered, "How can the guests of the bridegroom mourn while he is with them? The time will come when the bridegroom will be taken from them; then they will fast. -Mt. 9:15 Oops.

Guests of the bridegroom are not the bride. Oops.

[Salvation]

The Church is Christ’s bride.

He's referring to his Apostles, later the first Christians, who had just been criticized for not fasting. So I don't see how your distinction applies.

Also, Jesus said: "When you fast, do not be somber like the hypocrites, for they disfigure their faces to show men they are fasting. Truly I tell you, they already have their full reward. But when you fast, anoint your head and wash your face, so that your fasting will not be obvious to men, but only to your Father, who is unseen. And your Father, who sees what is done in secret, will reward you."

That's Jesus, saying among other things that the Father will reward you for fasting.
