Yeah, I believe in what the Holy Bible says happened in the four gospels. He died on friday and rose Sunday morning, thus the early church, that was made up of Jewish christians in Jerusalem began meeting together and bringing their offerings on the first day of the week which is Sunday. I dont try to fit the events of Jesus' death, burial, and ressurection into a formulated set of rituals that had to be done in some exact certain way or it didn't work. He kinda came to do away with all of that, he being the one sacrifice once, for all of us. The main thing is to trust in what he did on that cross as payment for our sins and turn from our way of obtaining eternal life, to God's way that he said, in Isaiah 53 that he was satisfied with the payment. Jesus paid for our sins and offers salvation as a free gift to all who will believe in or trust in him, that he is the lamb of God that takes away the sin of the world.
