Are the contents of the Jehovah Witness website dogmatic? Is the content of the Jehovah Witness website final and binding? 

For example, is the Bible Study guide definite and binding to all the Faithful? Or is it a usefull study guide that is open for the Faithful to critique.
The main site of jw.org contains the most up-to-date information on what Jehovah's Witnesses believe, so it's authoritative in that sense, but it isn't as authoritative as the Bible. The website is updated over time, and new clarifications are published yearly.

2 Timothy 3:16, 17 (NWT)
16 All Scripture is inspired of God and beneficial for teaching, for reproving, for setting things straight, for disciplining in righteousness, 17 so that the man of God may be fully competent, completely equipped for every good work.

There's a concept Jehovah's Witnesses have called &quot;making the truth your own.&quot; Nobody is expected to blindly believe in something just because the website or one of the publications says it. If someone finds something they don't understand or agree with, that's a great opportunity to do more research on the subject.

Matthew 15:7-9 (NWT)
7 You hypocrites, Isaiah aptly prophesied about you when he said: 8 ‘This people honor me with their lips, but their hearts are far removed from me. 9 It is in vain that they keep worshipping me, for they teach commands of men as doctrines.’”



Acts 17:11 (NWT)
11 Now these were more noble-minded than those in Thes·sa·lo·niʹca, for they accepted the word with the greatest eagerness of mind, carefully examining the Scriptures daily to see whether these things were so.
