I found this paragragh, just down the page from the one you pasted, to be revealing - I wonder how your 'elder' would react to it?
TO AVOID BECOMING PREYHOW
Since twisted and counterfeit words and lip service to the Holy Scriptures are seen to be the point of departure from what is sound and true, it follows that our protection must be in a strong faith in the written Word of God. Tradition will not suffice; nor will some isolated Bible text that is interpreted in such manner as to do violence to the other plain teachings of the Bible. Whatever anyone asks you to accept as truth, be sure to require of him some clear basis for the teaching in Holy Scripture. Even as regards the religious association to which you now adhere, do not hesitate to inquire into the Scriptural foundations for its teachings. All of this means that you must be a diligent student of God’s Word. Paul counseled the young man Timothy: "Continue in the things that you learned and were persuaded to believe, knowing from what persons you learned them and that from infancy you have known the holy writings, which are able to make you wise for salvation through the faith in connection with Christ Jesus." (2 Tim. 3:14, 15) So, too, if you have been taught from the Holy Scriptures, continue to study them. WT 11-1-64 page 646
