The following paragraph (excerpted from the linked post) is certainly true of the New Testament church. However, today’s church – especially in America – teaches much more about church than it does about Christ.
Christianity, in these and texts like them, is described as the faith, the truth, the pattern of sound words, the traditions, the sound doctrine, and what was delivered in the beginning. This is what the apostles taught, it is what they believed, it is what they “delivered” to the church, it is what is “entrusted” to the church. Christians are those who “believe” this teaching, who “know” it, who “have” it, who “stand” in it, and who are “established” in it. The New Testament letters were written to remind believers about their responsibilities in relation to this teaching, this faith that has been delivered to the church in its final and completed form. The apostles, we read, write to “remind” them of it, urge them to “pay close attention” to it, to “stand firm” in it, to “follow” it, to “hold” onto it, to “guard” it as one might a precious jewel, and to contend earnestly for this truth.
