Abstract During its history, Christianity, including Protestants, has encountered different challenges. One of these challenges is the emergence of liberal theology. What reaction did the religious reformation movement, which came to existence in the sixteenth century with the aim of reviewing Christian beliefs, have against the mentioned challenge? That a movement wants to reconsider religious believes with new perspectives implies that it will ignore or reject some principles; while, the Protestant church shows, through its adherence to the primary beliefs of the church such as the Trinity, Incarnation and Sacrifice, that it has resisted the above-mentioned challenges, and therefore has not undergone many changes.
