All believers indiscriminately are commanded to search the Scriptures - 2 Tim. 3:15,17; Acts 17:11; John 5:39. Add to this the overwhelming message of the OT that God’s Word is to light the path of His children.
Do you think what we find in Scripture are suggestions and not commands? Verse 15 says “from a child” so obviously Scripture has been studied(searched) from childhood on. Especially considering how it is through Scripture we become saved
”… which are able to make thee wise unto salvation through faith which is in Christ Jesus.” So, downplaying Scripture, or sometimes even just dismissing it, does a grave disservice to those seeking salvation.
In Acts 17:11 we see how the Bereans were commended because they:
”…searched the scriptures daily, whether those things were so.” And here the explicit imperative to:
”Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.” So, yes by God’s mercy, we are commanded to “search the Scriptures.”
John 5:39 is no “retort”, at least according to many theologians - The word may be either in the indicative or imperative mood. In our translation it is in the imperative, as if Jesus commanded them to search the Scriptures, Cyril, Erasmus, Beza, Bengel, Kuinoel, Tholuck, De Wette, and others, give it as in the indicative; Chrysostom, Augustine, Luther, Calvin, Wetstein, Stier, Alford, and others, regard it as in the imperative, or as a command.
However, that does not give them carte blanche licence to interpret Sacred Scripture contrary to the fundamental teachings of the Catholic Church.
No one needs any license, cart blanche or otherwise, to reject the RCC’s interpretation of the few verses it has actually interpreted. The RCC is not mentioned in Scripture, ditto for the pope, magisterium, “infallibility” and a host of other RCC specific dogmas.
Did the Bereans seek interpretation from anyone?..no, they searched for themselves which is in fact what God commands. God gives plenty of commands(not suggestions) to “search the Scriptures”
ourselves because it is in them we find Him. And as Paul, under the inspiration of the Holy Spirit, told Timothy it is God’s words which bring salvation. Throughout the entirety of the Bible, God speaks of His holy words, His commandments, His statutes and Jesus does the same in the NT. Over and over He says
"it is written". To
“search the Scriptures” is no less a command than to
“believe and repent”.
