Twenty centuries of change and innovation have so altered the face of Christianity that its modern form often differs remarkably from the original.
In its pure form, however, Christianity is clearly described for us in God’s word. Furthermore, we are strictly forbidden to tamper with it: “But though we, or an angel form 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 1:6-9)
If we were to start with the Bible itself as our guide, dropping both the traditions of our forefathers and the innovations of modern culture, we would again have Christianity in its pure form as envisioned by Christ and taught by His apostles.
