Jews and Christians have not observed Leviticus’s instructions for animal offerings since the 1st century AD, following the destruction of the Second Temple in Jerusalem in 70 AD. As there was no longer a Temple at which to offer animal sacrifices, Judaism pivoted towards prayer and the study of the Torah, eventually giving rise to Rabbinic Judaism.
And if ye salute your brethren only, what do ye more than others? do not even the publicans so? Matthew 5:47 KJV
