Why Do Jews and Christians Have Different Sabbath Days?

Have you ever wondered why we celebrate the Sabbath on Sunday? Have
you asked yourself, what does Jesus mean when he says, “Think not
that I have come to abolish the law and the prophets; I have come
not to abolish them but to fulfil them." (Mt 5:17) And why does
this new covenant change the Sabbath? "...This cup which is poured
out for you is the new covenant in my blood." (Lk. 22:20) Today,
Fr. Mike delves into the scriptural roots of the Sabbath and why we
as Catholics celebrate it on Sunday and not Saturday as the Jewish
people still do today.
