as priests, the ekklesia are not intermediaries between anyone else and yhvh, we serve as priests only in yahushua.
in the body of the messiah on earth, there are no intermediaries between any person and yhvh, except yahushua - he is the one faithful and true, the messiah, savior and friend of sinners who came to save us.
absolutely no human called a priest nor a minister today is an intermediary between yhvh and men, except for prayer - which is entirely different than standing in the gap for sin. any and every man who makes any claim to being an intermediary for sin is deceived and deceiving, as only yahushua is able to redeem man, to atone for sin, to take the place/suffer the penalty for anyone else's sin, to save anyone.
a large number of groups all over the world make claims that they can save someone, but they aren't able to and they don't pass the test of scripture(which read to see - read HEBREWS first if you want to know the truth).
