On April 18, 1521 at the Diet of Worms, Johann Eck adjured Martin Luther under oath to renounce his biblical teaching and faith – both of which radically conflicted with that of Catholic Rome. Luther responded thus:
Since your most Serene Majesty [i.e. Charles V], and your High Mightiness, require from me a direct and precise answer, I will give you one, and it is this. I cannot submit my faith either to the Pope or to the Councils, because it is clear as day they have frequently erred and contradicted each other. Unless, therefore, I am convinced by the testimony of Scripture, or on plain and clear grounds of reason, so that conscience shall bind me to make acknowledgment of error, I can and will not retract, for it is neither safe nor wise to do anything contrary to conscience….HERE I STAND. I CAN DO NO OTHER. MAY GOD HELP ME. Amen. [brackets mine]
Firmly convinced of both the biblical Gospel and the errors of Rome, Luther staunchly refused to recant anything. Like Luther, believers must be firmly grounded in biblical doctrine. Why is a solid foundation in biblical doctrine absolutely necessary for a Christian? For the following reasons: (1) to live a godly life in Christ Jesus through the Holy Spirit’s power; (2) to be protected from theological and spiritual error; (3) to accurately preach the biblical Gospel to both believers and unbelievers; (4) to be able to teach and disciple others; and (5) to be able to defend the Christian faith. Accordingly, the purpose of this blog series is to equip believers (both young and mature) with a concise, yet faithful, summary of the essential tenets of the Christian faith – in other words, basic Bible doctrine. Like Luther, let us resolve to live for God, even if no one else will – even in the face of unflinching opposition.
