I must prepare to travel this weekend, and therefore do not have the freedom to answer your sitting duck questions just now. Perhaps after the traveling is over. But I already dealt with literal interpretation in an earlier post. Your questions challenge the validity of some church denomination rather than the method of interpretation, so they are essentially indirect ad hominem type sideswipes anyway. So, later.
You have apparently missed the point. Do you believe that it is a good idea for some johnny come lately church to tell the Original Christian Church that it is not spiritually mature. The Catholic Church is the one that infallibly defined each of these doctrines that most of these churches adhere to and did it before these newbies were glimmers in their founders eyes.
What members of your church attended the Council of Nicea to fend off the gnostic and Arian heresies? Which of them put down the pelagius heresy.
The "members" of the church of Jesus Christ, His body, consists of ALL believers and followers of Jesus Christ from all time, so those who counted on Divinely-inspired Holy Scripture to dispute the heretics back then are as much members of the body of Christ as those of us who follow him today. Today's Roman Catholics like to claim they are members of the same church as the early Christians and that ONLY their current church is the same one as established in that first century. This can easily be shown to be in error as there are many doctrines and dogmas that they hold to today that were unheard of in the Apostles' time or that have CHANGED since then.
Where was your church during the Council of Constantinople that settled the matter of the filoque?
See above answer. As a side note, are you implying that the Orthodox Church, which disagrees with the "filique" of the Roman Catholic Church, is not equally as genuine as they are?
Can you identify the members that helped to define the doctrine of the hypostatic union? Which of them was present at both Hippo and Carthage ordering the canon of the New Testament?
See answer to first question. See how easy it is to settle false constructs once one has the actual truth revealed? Where were "our" church members back then? The same place as those who hold to the Biblically revealed Christian faith today.
