You guys should look up how magic typically works. A witch's power is irrelevant when it comes to spellwork. Spells (incantations and rituals) work by calling upon the power of other things more powerful than the witch. Why do you think Sam, Dean, and Bobby were able to bind Death, a being whose power rivals God's, even though they weren't witches? They used Dean's (IIRC) blood (for the spell to bind Death to him, specifically), a bunch of herbs (there are always herbs in spellwork, usually to "boost" everything else), and "an act of God, crystallized forever" (essentially, God's power in physical form).
