Chapter and verse where Scripture says to throw out a portion of the Old Testament and to rely exclusively in personal interpretations of what isn’t thrown out.
We don’t throw out the Old Testament. We also don’t rely on a fallible human institution to do our thinking for us given its poor track record. The Catholic Church put Galileo under house arrest for his heliocentric papers (which were correct). Any church that incorporates torture and death to its critics would not be fit to interpret Scripture for me.
