What is the Apostles doctrine?

What does it mean to follow the apostolic doctrine? Better yet to be a member of the Apostolic Church.? Surely it was a commandment for the Apostles to go and teach ALL nations what they were commanded by Christ. What was it exactly that Christ taught the Apostles and does today “Apostolic Church” teach what the Apostles of the New Testament taught? Is there any correlation between the Old Testament prophets and the New Testament Apostles? Are today's Apostolic church leaders misleading the multitude or drawing them closer to eternal salvation? Anyone who is a part of this growing movement might want to tune in Tuesday night at 8PM central. Things aren’t really what they seem!
