We do have verses in the Old Testament of necromancers and spiritists with God forbidding His people from appealing to the dead through them. It is written in the Law. Consider for instance the example written of Saul, who called upon the spirit of Samuel after he died, through the woman of Endor who was known for her ability to call upon dead spirits. (see 1Sam 28)
Just as God forbade His people of Old from calling upon necromancers and spiritists to speak with dead spirits for them, since God is the same yesterday, today and tomorrow, it would be foolish to believe Christians in the New should call upon spirits of the dead.
Leviticus 19:31 (KJV) Regard not them that have familiar spirits, neither seek after wizards, to be defiled by them: I am the LORD your God.
De 18:10 There shall not be found among you any one that maketh his son or his daughter to pass through the fire, or that useth divination, or an observer of times, or an enchanter, or a witch,
De 18:11 Or a charmer, or a consulter with familiar spirits, or a wizard, or a necromancer.
De 18:12 For all that do these things are an abomination unto the LORD: and because of these abominations the LORD thy God doth drive them out from before thee.
If it's wrong to call upon dead spirits for enchanters, witches, charmers or consulters of familiar spirits, wizards or a necromancer, than when we call upon dead spirits haven't we then become one that does that thing which God forbids.
Not only is there no explicit command for us to pray to dead spirits, as I've shown there is clear prohibition for doing so, for it is an abomination unto God.
I have no intention of turning this into a debate over the manuscripts. The only reason I mention Maccabees is because you brought up Catholic tradition that includes books the Church determined should not be included with the Sacred Texts of Scripture. Enough said about that.
I think you're conflating two different things.
The passages in Leviticus 19 and Deuteronomy 18 condemn necromancy, divination, mediums, spiritists, and attempts to obtain secret knowledge through the dead. Saul's sin in 1 Samuel 28 was not simply that Samuel was alive before God. Saul sought out a medium whom God had explicitly forbidden after God refused to answer him, and he attempted to obtain revelation through occult means.
Catholics reject those practices as well.
Asking a saint to pray for us is fundamentally different from consulting a medium, attempting to summon spirits, practicing divination, or seeking hidden knowledge from the dead. Catholics are not attempting to conjure Mary, obtain secret information, predict the future, or bypass God. The request is simply, "Please pray for us."
If the two practices are truly the same thing, then that still needs to be demonstrated from Scripture rather than merely asserted.
You also state that there is a "clear prohibition" against asking saints for intercession. However, the passages you cite prohibit necromancy and consulting familiar spirits. They do not discuss asking glorified members of Christ's body to pray for us.
There is a significant difference between:
- "Tell me the future through a medium."
- "Pray to God for me."
Those are not the same act.
As for Revelation, you said:
"These heavenly beings present the prayers of ALL saints who offer up prayers to God..."
Then we already agree that heavenly beings are involved in presenting prayers before God. The remaining question is why you assume that no glorified human saint can participate in that heavenly ministry. I do not see where Scripture makes that distinction.
Revelation shows heavenly beings presenting prayers before God. You interpret those beings as excluding departed believers, but the text itself does not say that. Since you acknowledge that those in Christ are alive in Heaven, the burden is on you to show where Scripture teaches that angels may participate in presenting prayers before God but redeemed saints may not.
Regarding 2 Maccabees, simply calling it "Apocrypha" does not address the example it contains.
The passage still depicts the prophet Jeremiah, after his earthly death, praying for God's people. If you reject that evidence because you reject the book's canonicity, then we have shifted from discussing the intercession of saints to discussing the canon of Scripture.
The passage remains a direct example of a righteous departed saint praying for God's people. If you reject that evidence, the discussion becomes: why should 2 Maccabees be excluded?
You argue that Maccabees lacks prophetic authority, contains doctrinal discrepancies, and was excluded from the Hebrew canon. But those points do not establish the Protestant canon; they are reasons Protestants give for preferring it.
Why should Christians be bound to the canon recognized by later rabbinic Judaism rather than the canon received and used by the early Church?
Moreover, if prayer for the dead or the intercession of the righteous departed is one of the reasons for rejecting 2 Maccabees, that seems circular. It assumes those doctrines are false and then uses that assumption as grounds for rejecting a book that contains them.
In any case, rejecting 2 Maccabees does not answer the example it contains. It simply moves the debate to a different question: by what authority is 2 Maccabees excluded from Scripture?
Finally, even if I granted your entire argument for the sake of discussion, you still would not have established your earlier claim that Marian devotion is idolatry. At most, you would have argued that asking saints for intercession lacks biblical warrant. That is a different claim from saying Catholics worship Mary.
To show idolatry, you must demonstrate that honoring Mary or asking for Her prayers is equivalent to offering Her the adoration due to God alone. That point still has not been demonstrated.
