I think that it’s important to remember that, for all intents and purposes, Catholic churches, basilicas, cathedrals, etc are temples, in the tradition of the Old Testament tabernacle and temple(s). I always like to quote one of the “praises” of the book “
The Church: Unlocking the Secrets to the Places Catholics Call Home” by Cardinal Donald Wuerl and Mike Aquilina:
“
What the Temple was to the Israelites, our churches are for us Catholics. They are sanctuaries of God’s presence-the meeting place of Heaven and Earth”-Dr. Scott Hahn.
Another amazing book related to this issue (and others) is “
The Crucified Rabbi: Judaism and the Origins of Catholic Christianity” by Dr. Taylor Marshall.
Anyway, my point is that Catholicism continues ideas and practices related to the Israelite tabernacle, temple, and other Jewish practices, many of which are not found in the LDS temples. These include things like ritual purification with water/ablution prior to service in the sacred space (as well as a priestly self-purification with water at appointed times), altars on which sacrifice is offered, a sacrificial priesthood, a perpetual sancutary lamp, offering of bread and wine (i.e. Bread of the Presence), singing of psalms, a gathering place for holy festivals/feast days, incense, etc. So, while it’s clear that the sacrifices offered in the Israelite temple are no longer necessary from the Christian perspective, it’s also clear that Catholicism has inherited much from the temple tradition (and that the Catholic priesthood is understood to be offering the
sacrifice of the Mass), and continues directly in that vein.
Latter-day Saints build temples for a number of reasons. They perform various ordinances there, such as baptisms for the dead (as well as all other ordinances for deceased persons), sealings (eternal marriage), and the Endowment. Mormons believe that temples are special places where God’s presence is in a special way, and they make covenants there.
