Well if there is a trinity then how can you explain the part where stephen says he sees jesus sitting at the right hand of God?
That would not be an argument against the Trinity. The trinity-doctrine is clear on the three being separate in person, the same in essence (but all part of the "God-head"). The confusion arises of course, because both the Father and the Son are referred to as "God".
The bible tells me jesus was an angel after his resurrection . Remember he kept appearing and disappearing walking thru doors ........... That would quite a feet for a human .
This is the view of the WTS, that Jesus` ressurection was "spiritual". I don`t agree with this, as it would nullify the hope given to mankind, thru the ressurection. If Jesus was "ressurected" solely as a spirit creature, then where do you (or the WTS) ever get the belief that you will be ressurected to live on earth? Without a pysical, bodily ressurection, the ressurection of Christ sets no presedence for the future ressurected state of the departed. The whole point of the ressurection has to be that it is primarily physical (but perfected), otherwise Jesus ressurection was no promise given to mankind about a future (physical) ressurection.
