The point of contention here, it that there is absolutely no precedence for using quotation marks, chapter and verse, as a disqualifying criticism against other followers of Christ...except by the church in contemporary times. On the contrary, there is every precedence for not using them, including Christ.
But it is good point also, that reading the scriptures was and is important. However, it is all the more important for our time, not to continue in the same practices of that former time, but rather to press on to perfection, leaving behind the elementary principles of Christ.
