Part 2
This conception of church/ekklesia/synagogue was understood by both Jews and Christians to be precisely not a TEMPLE. Both the Jewish temple and pagan temples were understood as the place where God lived. Early Christians had a clear choice for conceiving their buildings as gathering places (synagogues) or as replacements for the Temple in Jerusalem. They chose gathering places.

The PRIMARY focus on the Eucharist as an object of adoration, as the centre piece in a Temple--instead of the "glory" of Yahweh or instead of  a pagan idol --displaced the scriptural notion of the Eucharist as food in the middle ages precisely at the time the faithful we told they were not worthy to receive the sacred food and began not receiving communion almost all of the time they attended mass. Their "consolation prize" was the opportunity to adore the sacred host and chalice as they were elevated at mass; and the opportunity to worship the Eucharist in a tabernacle whenever they visited a church.
