NSTI Student Member Paul C asks:
I also hope Taylor could address Seventh Day Adventism in a video.
My in-laws are Adventists and a few are curious about Catholicism. At family get-togethers I’ve gotten questions, such as, wasn’t Constantine the founder of the Catholic Church? and, didn’t a Pope change the Sabbath day in order to attract converts from followers of a Sunday pagan ritual? They’ve been taught a lot of misinformation!
Clearly Constantine was not the founder of Catholicism. See our video(s) on Constantinian era on this.
Regarding Sunday, it goes back to the Apostles:
“And on the first day of the week, when we were gathered together to break bread, Paul began talking to them, intending to depart the next day, and he prolonged his message until midnight,” (Acts 20:7).
Here Saint Paul is breaking bread (Eucharist) and preaching on Sunday.
Saint Paul also recognizes Sunday as the day of Christian gathering here:
“On the first day of every week let each one of you put aside and save, as he may prosper, that no collections be made when I come.” (1 Cor. 16:2). So the offering was taken on Sunday – during Liturgy.
The Jews kept Saturday (last day of week) because they looked forward to Messiah. Christians keep Sunday (first day of the week) because we look back to the Messiah.
Moreover, Christ rose again from the dead on Sunday and the Holy Spirit descended at Pentecost on a Sunday. Christ is King of the New Creation and so Sunday, the day of creation is the day of His worship.
Seventh Day Adventists are thus Judaizers and they do not understand the fulness of Christ’s fulfillment of not only the Old Law, but the Old Creation. If you want to see study how Christ fulfills the entire Old Testament (including an appendix list of over 300 prophecies), see my book The Crucified Rabbi: Judaism and the Origins of Catholic Christianity.
