Let's begin a new study. What unites Christians across the board are an amazing number of truths. If we Protestants really believe that salvation is by faith then let's give our Catholic and Orthodox brothers and sisters some credit for faith, and let's give God some credit for blessing those with faith. I believe that all churches have some serious theological flaws. Literally nobody has perfect theology. However, we all believe in the importance of what Jesus and the apostles taught.
Here then are a large number of things that unite all Christians. By Christians, I am referring to Catholics, Eastern Orthodox, Oriental Orthodox and most Protestants. I do not include those cultish groups that reject what the Holy Spirit has been doing in the Christian churches for the past 2,000 years. You’ll understand what that means as you continue this journey. How surprised will you be to find out how much actually unites Christians!
Let's look at the first ten of who knows how many truths that unite all Christians (all quotes from the The World English Bible simply because it's in the Public Domain):

The same was in the beginning with God… And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.” (John 1:1-2, 14)
3. Gabriel and Zacharias
All Christians believe that Zacharias was mute until his son John the Baptist was born because he doubted what Gabriel told him. “Behold, you will be silent and not able to speak, until the day that these things will happen, because you didn't believe my words, which will be fulfilled in their proper time."
