The first Christians were,
like Jesus, Jews resident in Israel who worshiped on occasion in the
Temple in Jerusalem and weekly in local synagogues. Temple worship was
a ritual involving sacrifice, occasionally including the sacrifice of
animals in atonement for sin, offered to Yahweh until Jesus became the
final sacrificial offering on Calvary. The New Testament includes many
references to Jesus visiting the Temple, the first time as an infant
with his parents.
