Am I the ONLY One Bothered by the Assumption Taken by BSF that John the Apostle Wrote Revelation?

I have said repeatedly how scholars and mankind are not 100% sure that John the Apostle wrote the book of Revelation.  Yet in the Notes given by BSF for Lesson 2 they flat out say John the Apostle wrote Revelation and they cite the reasoning/proof in verse 1 of Revelation.

I’m unsure what NIV version BSF is using, but Verse 1 of Revelation in my NIV Bible says this:

“The revelation of Jesus Christ, which God gave him to show his servants what must soon take place.  He made it known by sending his angel to his servant John”.

I’m not seeing how “servant” is the equivalent to “apostle” because it’s not.  It’s not in the original Greek in which Revelation was written and it’s obviously not in English into which this was translated or it would say “apostle.”  Both very different Greek words and English words.

I’m irritated and a bit irate (hence this post).  It bothers me that BSF if presenting this as fact (which they continue to say throughout the notes with such things as John the writer of the book said in his Gospel and the like).

It casts doubt for me on the rest of what BSF is going to tell me.  If I can’t trust them to tell me the truth about a simple fact as John the Apostle may not have written Revelation, then how can I trust anything else they say about anything?

It’s the same argument I use with the Easter Bunny, Tooth Fairy, and Santa Claus.  If you lie to your kids about their existence, how can they trust you in the big things like there is a God?

This is proof you must use outside sources.  You must investigate yourself.  You must use other commentaries besides BSF (and, yes, BSF is a commentary on the Bible).  You must not believe everything you read.  You must pray and ask God to reveal the truth to you.

We will only discover the author of Revelation in heaven, and I’m fine with that.  What I’m not fine with is a bible organization that I love and cherish deceiving me.

What do you all think?  Am I wrong here?  Please leave a comment below with your thoughts on this matter and how it effects the rest of the study.
