No.
That's not what it "teaches".
What its teaching is.... "the reason many are sick", is because they have not understood that the "Lord's body" is their HEALING.
So, they take communion, not understanding the power that is found in that revelation, that they don't comprehend.
= to take the Communion unworthily, means that you take it not understanding who you have become in Christ.
See, ALL the born again, have been "made righteous" and exit as "one with God".. so, Salvation that we have received makes us WORTHY, and when you dont understand this, you are taking communion with the idea that you are not worthy, and that is why you wont be healed.
This is why "many DIE".
Its because they dont understand who they are "in Christ".. and when you dont understand this then you can't have any faith, and without that, Healing will never come.
So, the born again are to always take The Communion knowing they are made worthy, as every Son/Daughter of God, born again, is absolutely made worthy.
= Take the Communion in THAT Mind, vs...>"am i worthy"... which is the wrong mind.
