Evangelicalism currently has an incoherent relationship with Roman Catholicism. Many Evangelicals are uncertain about what Roman Catholics actually believe. Do they believe in the same Gospel, or something entirely different? This question is important for leaders of Evangelical churches and Evangelical believers across Europe and the world. According to the historic Protestant view, Roman Catholicism is a severely flawed system in need of a radical biblical reformation in its basic theology and practice. It is essential for Evangelical leaders, in a time of growing confusion regarding Evangelical identity, to understand why we believe what we believe, and to know how to explain the Gospel in a compelling and persuasive way.
