Paul was a Sabbath keeper along with Jesus and the early church.

upon the first day of the week, when we were gathered together to break bread, Paul discoursed with them, intending to depart on the morrow; and prolonged his speech until midnight.
1 Corinthians 16:1-2 (NASB)
[SUP]
1 [/SUP] Now concerning the
collection for the saints, as I directed the churches of Galatia, so do you also.
[SUP]

On the first day of every week each one of you is to put aside and save, as he may prosper, so that no collections be made when I come.
1 Corinthians 9:19-23 (NIV)
[SUP]
19 [/SUP] Though I am free and belong to no man, I make myself a slave to everyone, to win as many as possible.
[SUP]
20 [/SUP]
To the Jews I became like a Jew, to win the Jews.
To those under the law I became like one under the law (though I myself am not under the law), so as to win those under the law.
[SUP]
21 [/SUP]
To those not having the law I became like one not having the law (though I am not free from God's law but am under Christ's law), so as to win those not having the law.
[SUP]
22 [/SUP] To the weak I became weak, to win the weak. I have become all things to all men so that by all possible means I might save some.
[SUP]
23 [/SUP] I do all this for the sake of the gospel, that I may share in its blessings.
Sabbath NEVER became Sunday, that purely in the made up theology of the Adventists minds and their so-called prophet Ellen White.
We worship on SUNDAY, because Jesus rose from the Grave on Sunday. The First Fruits of many resurrections to come; and the Festival of First Fruits was ALWAYS celebrated on a SUNDAY.
Leviticus 23:10-12 (ASV)
[SUP]
10 [/SUP] Speak unto the children of Israel, and say unto them, When ye are come into the land which I give unto you, and shall reap the harvest thereof, then ye shall bring the sheaf of the
first-fruits of your harvest unto the priest:
[SUP]
11 [/SUP] and he shall wave the sheaf before Jehovah, to be accepted for you:
on the morrow after the sabbath the priest shall wave it.
[SUP]
12 [/SUP] And in the day when ye wave the sheaf, ye shall offer a he-lamb without blemish a year old for a burnt-offering unto Jehovah.
