[P-Marlowe]

The difference in the focus is because we believe that God is THERE, on the altar and in the Tabernacle, body and blood, soul and divinity, under the appearances of bread and wine. If you believe that, it changes the entire focus of the worship service.

You almost make it sound as if God is not present when the eucharist is not being served. IOW God's presence in a person exists only when they are partaking of physical elements.

Is not God everywhere... always? Has he not taken up tabernacle in your body and soul?

Or is he only really present in the Eucharist?

Protestants (or at least this one) believe that God is omnipresent and further that when a person becomes a believer, God takes up actual residence in that person. So there is no necessity of insisting upon a "real presence" in the eucharist since the "real presence" is in the heart of the believer.

[AnAmericanMother]

Of course God is everywhere, but Christ himself has deigned to become physically present in the Blessed Sacrament.

When the Eucharist is not being served, the Tabernacle is used for reservation of the Host.

You can tell because the lamp is lit beside the Tabernacle. When it is, one reverences the Tabernacle instead of the altar.
