one true church from scripture

 also from comment 83 here http://www.calledtocommunion.com/2013/01/holy-church-finding-jesus-as-a-reverted-catholic-a-testimonial-response-to-chris-castaldo/#comment-47418

 but you think that this organised body, having produced the New Testament, signed off on any further (earthly) authority, leaving you with the New Testament itself and your own understanding to interpret it. Catholics do not think the Church did, in fact, thus cease to possess its (highest earthly) authority. “He who receives you receives Me, and he who receives Me receives Him Who sent Me.” We think that ‘you’ continues. We think God intended that so that we would not have to hope that we have understood the Scriptures correctly.
