It is forbidden in the WT, therefore a DF offense. Can't have you read the bible alone, you may see that that it contradicts the WT.
“Thus the Bible is an organizational book and belongs to the Christian congregation as an organization, not to individuals, regardless of how sincerely they may believe that they can interpret the Bible. For this reason the Bible cannot be properly understood without Jehovah’s visible organization in mind.”—WT Oct 1, 67 pg 587
“We all need help to understand the Bible, and we cannot find the Scriptural guidance we need outside the ‘faithful and discreet slave’ organization.”—WT Feb 15, 81 pg 19
“They say that it is sufficient to read the bible exclusively, either alone or in small groups at home. But, strangely, through such ‘Bible reading,’ they have reverted right back to the apostate doctrines that commentaries by Christendom’s clergy were teaching 100 years ago…”— WT Aug 15, 81 pg 29
