-Removed-For the third time, the answer is: all the churches which can trace their lineage back to one of the Apostles. This includes not only Catholicism, but Greek and Russian Orthodoxy, as well as the Armenian and Coptic churches, and any other church which can trace its lineage back to someone who was himself authorised by Jesus.
I am not now nor have I ever been a Christian, closet or otherwise.
I can accurately report what Judaism is, or Buddhism or Islam or animism, without defending them or believing anything they claim. Same with Christianity.
-Removed-The lineage going back to an Apostle, and ultimately to Jesus, is maintained and carried out by a ceremony, "The Laying On Of Hands," which confers authority (e.g., ordination) and invokes the Holy Spirit (the primary channel, remember).
This act of laying on of hands, invoking the Holy Spirit, is mentioned in the NT, for example: Acts 6:5–6, Acts 8:14–19, Acts 13:3, 1 Timothy 4:14. Also possibly Acts 14:23.
I'm not asking you to believe me; ask those who have received the authority and the blessing from him whom you worship.
It rather surprises me that you seem to have no knowledge of this, as it pertains to the elementary inner workings and detail of how the salvational message is propagated in Christianity.
Whether I personally believe any of this has no bearing on the discussion, just as I am quite happy to discuss evolution with people don't believe it.
