However, if by "Bible" you mean an infallibly defined canon to which all are to submit, then Rome did have a bible until after the death of brother Luther, which put an end to debate. “The Council of Trent definitively settled the matter of the OT Canon.

Paul, a servant of God and an apostle of Jesus Christ, for the sake of the faith of God’s elect and their knowledge of the truth, which accords with godliness, in hope of eternal life, which God, who never lies, promised before the ages began and at the proper time manifested in his word through the preaching with which I have been entrusted by the command of God our Savior;

One of the Cretans, a prophet of their own, said, “Cretans are always liars, evil beasts, lazy gluttons.” This testimony is true. Therefore rebuke them sharply, that they may be sound in the faith, not devoting themselves to Jewish myths and the commands of people who turn away from the truth. Titus 1:12-14 (emphasis added to save the rapid reader)
God is Good and His Word is True.
