For from the rising of the sun, even to its going down, My name shall be great among the Gentiles; In every place incense shall be offered to My name [Non-denominational churches do not burn incense to the Lord. The Catholic Church does.],
And a pure offering [Non-denominational churches consider their communion wafer neither pure nor an offering. The Catholic church considers its Eucharist pure (it’s the body of Christ), and an offering (it’s the very sacrifice that Christ made at the Last Supper, not an additional one, not a different one, not a new one every time, the same one, it’s the same time-transcending sacrifice that Christ made at the table with his Apostles, just as Christ had no beginning and has no end, neither does his one sacrifice). ~ Malachi 1:11
But every Lord’s day gather yourselves together, and break bread, and give thanksgiving after having confessed your transgressions [sounds like modern-day Catholic Confession], that your sacrifice may be pure [sounds like modern-day Catholic Eucharist]. But let no one that is at variance with his fellow come together with you, until they be reconciled [what does that say about those who don’t believe the Eucharist to be a pure sacrifice? what does that say about those who consider communion to be a purely symbolic act with no sacrificial value?], that your sacrifice may not be profaned. For this is that which was spoken by the Lord: In every place and time offer to me a pure sacrifice; for I am a great King, says the Lord, and my name is wonderful among the nations. ~ The Didache, Chapter 14, written 70 A.D.
The Old Testament confirms the sacrificial nature of the Eucharist (and throws in a prophecy about Catholic incense). The earliest Christian writings confirm the sacrificial nature of the Eucharist (and throw in affirmation of Catholic Confession). The Eucharist is sacrificial. It is the body of Christ.
The Bible is always proven true.
