THE SCRIPTURES PRE-EXIST THE CHURCH
Timothy was born at Lystra and had a Greek father and a Jewish mother. His grandmother (Lois) and mother (Eunice) taught him the scriptures from childhood. So, when Paul wrote these words to Timothy, he was referring ONLY to the Old Testament Scriptures:
"And that from a CHILD thou hast known the holy scriptures, WHICH ARE ABLE TO MAKE THEE WISE UNTO SALVATION THROUGH FAITH WHICH IS IN CHRIST JESUS. All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness." 2 Tim 3:15-16
An Old Testament saint, Timothy's grandmother, believed in Jesus because the scriptures testified of him. That second letter of Paul to Timothy (Now part of The New Testament) gives us irrefutable evidence that The Old Testament Scriptures have greater authority than the traditions of the church.
