First men, then animals, then God/Jesus, then doves, now tithes and 'the eucharist'.

Early Christians did that? Where do you get that from? It was the eucharist all the way till today. Tithe is nothing to do with sacrifice - it's a duty for every Christian to be charitable and help the Church but no one is forced to give back.

Mistaking man's constantly changing interpretation for God's WORD (truth) is what leads to error.

Again, it's not constantly changing. If it were the case, what makes your interpretation not subject to said constant change? Suppose your interpretation is correct, how do we know it will still be valid tomorrow? This leads to epistemological nihilism - the inability to have knowledge of the thing in question at all.

You probably don't realize how each book of the old testament is testament to the failure of the time's religion to come to ultimate truth and so was doomed to CHANGE.

Truths can't be disproven. And only Truth is eternally unchangeable.

This is your gnostic interpretation of the text which you base on your gnostic worldview and its ruling presuppositions. The Christian interpretation shows perfect continuity in both the OT and the NT. What is the "ultimate truth" in your worldview, do we have access to it and if so, how? Where do you get the standard for truth?
