[Hermann the Cherusker]

Which day of the week is The Sabbath? The first or the seventh?

In the Catholic Church, the Sabbath is Saturday. In our Liturgical Books, it is clearly called "Sabbato" in Latin - "Sabbath".

The obligations of the 4th Commandment, however, are transferred from the Sabbath, and the Jewish feasts ordained by God through Moses and by the High Priest (i.e. Hannukah), to the Lord's Day, and Christian feasts created by the Church by the Pope (i.e. Christmas, Ascension, All Saints, etc.).

[P-Marlowe]

The obligations of the 4th Commandment, however, are transferred from the Sabbath, and the Jewish feasts ordained by God through Moses and by the High Priest (i.e. Hannukah), to the Lord's Day, and Christian feasts created by the Church by the Pope (i.e. Christmas, Ascension, All Saints, etc.).

By what scriptural authority did the Pope do that?
