Not sure if this is being posted in the right place, but I have some questions about Jesus.
- What did Jesus change? Did he overturn parts of the old testament? If a first century observant Jew became a Christian, how did his life and behavior change?
Jesus fulfilled the Old Testament and established a new one
a first century observant Jew wouldn’t have to change much because Jesus is the Messiah they have been waiting for. some accepted him, some didn’t
- When did the Sabbath day change to Sunday?
it didn’t. Sunday is not considered a Sabbath day, Saturday is still the Sabbath. early Christians used to go to the Temple or Synagouge on Saturdays and then celebrate the Lord’s Supper on Sundays. this is until there was so much backlash from the Jews of the time that they made it mandatory for those who enter the Temple and the Synagogues to renounce Jesus. of course the Christians wouldn’t do that, so they stopped observing the Sabbath
- Jesus was supposed to be in the tomb for 3 days, but it doesn’t look like 3 days to me when I read the Bible!
the concept of time for Jews are different to how to count time today. its quite possible that Jesus was in the tomb for a little over 24 hours
day 1, Jesus died on the cross at around 3pm. he has to be burred before the sun sets because for Jews, the new day begins when the sun sets (or the current day ends when the sun completely sets). so by that evening it was already the Sabbath, a new day for them, so its day 2
next morning the sun rises and then sets later in the day, thats day 2
as soon as the sun sets on day 2, its the beginning of day 3. so if the sun sets at 6:30pm and Jesus rose at 6:31, then he would have been in the tomb a total for 27.5 hours. but for Jews, they count those as 3 days
