Why do Catholics go to church on Sunday instead of Saturday?

Catholics go to church on Sunday because it was the day of the resurrection. Although the ten commandants say to keep holy the Sabbath day, this was part of the covenant with the Jewish. Catholics do not have to follow it because Jesus started a new covenant saying that it doesn’t need to be done. We don’t have a Sabbath day but we do have the Lord’s day, which is Sunday.
