It's amusing that recently you said that the watchtower is able to change their positions over time-re: Biblical understanding. But for some reason the early church can't learn and adapt as they progress through time.
The fact is- right now you don't need to concern yourself with the doctrine of men from hundreds or more years ago.
All we need to do is read our bible today. The concept is right there for us to see. Let the Holy Spirit open your eyes.
