Not only St. Joseph's name added to the Canon broke with a ancient tradition but the 1700+ years old Good Friday Prayer for the Conversion of the Jews was changed.
Doesn’t matter.
(1) Both these prayers were not from Christ, therefore they aren’t part of the Divine/doctrinal part of the mass, which is the ONLY part that can’t be changed.
The canon prayers were not part of Church tradition until the 400s with pope St Gregory the great (and this only for the Latin rite...not sure if other rites have an old Canon).
(2) they were added/created by the Church and an earlier pope, so they are part of the human/changeable part of the liturgy. A pope has the power to change human laws, however old.
(3) These changes do not affect the doctrine/theology/substance of the mass, either in its sacrificial nature or its purpose as the greatest prayer to God.
Not only are you “making a mountain out of a molehill” but you are making yourself a judge of the Pope, since you’re claiming that John XXIII doesn’t have the power to chnage what another pope added. Hogwash.
