“My words”?
Or God’s Word?
Leviticus 26:1 immediately comes to mind.
Isaiah 42:8
Isaiah 57:13
2 Kings 18:3-4
and of course - Exodus 20:4 would qualify as the “grand-daddy” regarding this issue.
All this being said - our desires can be idols. our habits or hobbies can be idols. What we eat or drink can be idols. Idols are anything that get the respect, reverence, attention, focus, worship, etc. that God deserves.
Again - I have yet to find in my years of extensive Biblical studies - ANY command or even suggestion that followers of Christ should worship/adore/revere ANYTHING or ANYONE but Jesus Christ alone.
And the referecne to relics raising someone from the dead- I assume you are referring to 2 Kings 13 when a man was cast into Elisha’s grave (presumably by accident because of impending danger). Where does that indicate that the “relics” were used intentionally by those burying the dead man? Further - how does this incident provide a defense for the collection and attempted USE (and the subsequent worship and adoration given the relics) of these items?
Closest thing I can find to the “collection” of relics advocated is when Moses carried the bones of Joseph. But what was the ultimate destination? That he might be buried in the promised land. NO indication is given for worship/adoration/mystical powers associated.
Notice that the location of Moses final grave is unknown even to this day... any guess why? Would the Hebrews not have worshiped the location and his remains? Quite possible, given the prominent position given to him.
“who said the Divine Liturgy over the bones or martyrs” - do you have any idea how silly (and unscriptural) that sounds?
According to the New Testament - how many real High Priests are there?
According to the New Testament, who is the only arbiter between mankind and God?
According to the New Testament - what are the “Saints” (lets not get into the definition as used by Paul just yet) doing when “seen” in Heaven? They are worshiping and singing to God. Not making petitions. Not interceding. For that is the position and job of God the Son - Jesus Christ.
