**Honoring the seventh day of the week is also no longer binding. Saint Paul states that the legal demands of the Old Covenant are canceled and explicitly mentions the Sabbath as one of these. We read how Christ **
“…having canceled the bond which stood against us with its legal demands; this he set aside, nailing it to the cross… Therefore let no one pass judgment on you in questions of food and drink or with regard to a festival or a new moon or a sabbath." **
The festival, new moon, and Sabbaths are references to the yearly, monthly, and weekly observances of the Mosaic calendar. Therefore the whole Jewish festal calendar including the Sabbath is no longer binding.
**Saint Paul rebukes the Galatians for reverting back to their Jewish customs and observance of feast days of the Mosaic calendar as if they were still binding. **
“…but now that you have come to know God, or rather to be known by God, how can you turn back again to the weak and destitute elemental powers? Do you want to be slaves to them all over again? You are observing days, months, seasons, and years. I am afraid on your account that perhaps I have** labored for you in vain." NAB**
** A reference to Sabbath (7th day), new moon (monthly), and festive (yearly) feast days of the Mosaic calendar.
“…Therefore let no one pass judgment on you … with regard to a festival or a new moon or a sabbath.”**
the Christians came together on the first day of the week is also found in Saint Paul’s writings. ****
**1 Corinthians 16:2
“On the first day of every week, each of you is to put something aside and store it up, as he may prosper, so that contributions need not be made when I come." **
Saint Paul thought that the most opportune time to collect funds for the poor was when they gathered for their celebration of the Lord’s Supper -the Mass.
**Saint Luke must have had a special purpose for mentioning that they “gathered” on the “first” day of the week in Acts 20:7. This is evident because no where else in Acts, with one exception, does he list the date or the day of the week that this or that momentous missionary journey began, or this or that significant event happened. This implies that Luke was intending to convey the special significance that the “first” day of the week had come to represent. **
CHRIST** HONORSTHE**** FIRST DAYOFTHE W**EEK
**This day replaces the Sabbath for the day especially consecrated to God by the community’s worship. Christians celebrated their worship service in each others homes. Acts 2:42-46 “And they devoted themselves to the apostles’ teaching and fellowship, to the breaking of bread and the prayers… breaking bread in their homes…” We can see in the New Testament the beginning of this substitution of the first day of the week for the seventh day that the Jews had honored. **
“On the first day of the week, when we were gathered together to break bread, Paul talked with them, intending to depart on the morrow; and he prolonged his speech until midnight." **
Here we see the two basic elements of Sunday worship which have been followed by the Church to this day: 1) the breaking of bread, which designates the celebration of the Lord’s Supper (Catholics call it the Mass); and 2) the sermon.
**Christians gathered on the first day of the week because that was the day of the Lord’s greatest triumph over Satan and death. Luke’s Gospel proclaims that Christ rose on the first day of the week. **
Luke 24:1, 2, 6, 7, 13, 19-21
“1. But at daybreak on the first day of the week they took the spices they had prepared and went to the tomb.
2. They found the stone rolled away from the tomb …
6. He is not here, but he has been raised. Remember what he said …
7. that the Son of Man must be handed over to sinners and be crucified, and rise on the third day.” …
13. Now that very day two of them were going to a village seven miles from Jerusalem called Emmaus …
19 … Jesus the Nazarene …
20. how our chief priests and rulers both handed him over to a sentence of death and crucified him.
21. But we were hoping that he would be the one to redeem Israel; and besides all this, it is now the third day since this took place.”
