“Iglesia” is church in Spanish. As to our understanding of “Church,” that depends on whether you are talking about Luther’s “psychic” understanding or Calvin’s more practical meaning. And, no Ekklesia meant assembly in the sense of a coming together of the members of the Polis, which means something more corporate than “congregation.” Protestantism is, of course, so relentlessly attached to philology because it starts out being led, most powerfully, by a professor of Old Testament. Naturally it sees the church as gatherings of individuals listening to hours of exposition of Scripture.
I suppose if a person is that shallow or new to the faith that would be the case. Those who wish to discuss in depth however would want to understand what the apostles wrote and what words they used and what they mean. You see, the apostles taught that if it didn’t come from them it was to be considered “another gospel” and the preacher of that gospel was to be “accursed”. “But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed.” Galatians 1:8-9
I’m sure you would agree that it would be wise to stay with what the apostles taught. If not, well…………..you can read the verse.
You can be assured I will not believe anything the apostles didn't teach.
