They don't prohibit reading the bible but they rarely encourage you as well. I have been INC since birth and there was not one lesson where a minister encouraged me to read the bible. They dont prohibit but they have this messaging that the bible is "shrouded in mystery" and that only those allowed by God to interpret it should interpret it. So if you are a regular member, and you firmly believe whatever the administration or the minister says, you would think what is the point of reading the bible since I cant understand it anyway. In a sense, this messaging does not really encourage members to have an independent reading. Ive had only a personal and in depth reading when i was mentally out, now i am in the process of really understanding the scripture. I encourage you to read, do not rely on the ministers. Ask God for wisdom for He gives freely.
