Short answer of course it is OK to use Hebrew Greek and Scholars. Bible Believers are not a bunch of ignoramuses!
Heres the rub, it depends HOW you use them.... A Bible Believer will know what is said etc but they are not like Bible correctors who love to parade their ignorance by quoting their miniscule knowledge of Greek/Hebrew or appealing to Dr.Flap Doodle or whoever.
As Bro.Avery has aptly stated in his posts, Bible Correctors want it both ways, they can use other authorities but when a Bible Believer confronts them with what should be an acceptable 'authority' to the corrector they cry foul.
It sure makes me wonder how sincere some correctors are when asking questions.
