Final answer:
True, Martin Luther claimed that only the scriptures were without error and that the church and its officials could err. This led to the core Reformation principle of 'Scripture Alone' for guidance in faith and was part of what sparked the Protestant Reformation.
Step-by-step explanation:
Martin Luther argued that the church and its officials were not infallible and that only the scriptures were without error, which is indeed a true statement. He believed that salvation was through faith alone and that the scriptures were the sole authority for Christian belief and practice.
In his famous Ninety-five Theses, Luther challenged the Catholic Church's practices, such as the sale of indulgences, and denounced the belief that salvation could be achieved through good works or purchased forgiveness.
Holding to the principle of Scripture Alone (sola scriptura), Luther's translation of the Bible into the vernacular and the invention of the printing press greatly contributed to the spread of his ideas. These actions were crucial to the Protestant Reformation, leading to a significant shift in the understanding of the Christian faith and the role of the church among followers of the new Protestant movement.
