Today I was thinking about how the 1st century christians had several congregations in place as well as a governing body. So I'm wondering is that a valid reason for there to be a current governing body today?
Also I've been contemplating the issue of preaching. For years the WTS has used Matthews 28:19,20 as the basis for EVERY witness to engage in preaching. However in that scripture Jesus is giving that command only to a select few disciples. Did that same command apply to other first century christians?
If someone could give me some insight on those 2 things I would greatly appreciate it. I want to be well prepared in the event my family counters with those lines of reasoning.
