For one thing, passing Judgement as that passage states is about passing judgement on one's sould, not on the dangers of what one believes. I think even your sect teaches that. So let's not try to pervert it into the common finger pointing of the secular who are dumb with regard to such matters and don't know any better.
One of the main differences between the Catholic Faith and most Protestant Faiths is that we Catholics do not believe that once you die, you stop being a part of the Church.
Where did you learn this fraudulent notion? Christians who Die in Christ who have been given eternal life are spiritually part of the body of Christ; but, their Bodies are gone and our ability to interact with them is cut off till we get where they are. That is scriptural. And Ecclesiastes Chapter 9 (yes read the whole chapter!) states plainly that those dead in the flesh have no more part in what goes on here. Deuteronomy among other books of the Bible expressly forbids attempts at communicating with the dead in all it's forms. Jesus taught us to pray to God, not to other People. Moses taught what God wrote with his own finger, that you shall not make images, you shall not bow to them, you shall not worship them, etc. Note that Not bowing nor worshipping in the wording is an either or. Two seperate things expressly forbidden in the same statement. These things we can find in scripture.
What can we not find in scripture? How about statements revoking all these commands of God for 100 Alex!
Instead, you are an even more complete part of the Church, and can still serve in its mission.
Nice spin. Still doesn't make praying to the dead any less a sin. Wow, poetry.
