I believe that Jesus is the only One that can change Saturday to Sunday. Also in the Bible it does not say anywhere to change Saturday to Sunday because of the resurrection, and we need to love Jesus every day, yes. But Saturday is the day we don't work (as it says on the Bible) and we dedicate all day to God. People usually get confused and that's normal. God bless you all!
The Bible does say that the Sabbath day was given to the Nation of Israel as a sign of the old covenant between them and God (Exodus 31:13, Ezekiel 20:12, Deuteronomy 5:14-15) with no teaching that it was also commanded of the Church to observe as a sign between the Church and God.
