Christianity & Liberalism by J. Gresham Machen is a classic defense of orthodox Christianity, written to counter the rise of liberal theology in the early 20th century. In this influential work, Machen explores the key differences between the teachings of liberalism and orthodox Christianity, particularly focusing on issues such as God and man, the Bible, Christ, salvation, and the church. His arguments stress the importance of maintaining scriptural doctrine as central to the Christian faith.
Originally published in 1923, Christianity & Liberalism continues to be a foundational work in Christian apologetics. It was named one of the top 100 books of the millennium by World magazine and one of the top 100 books of the 20th century by Christianity Today. This book remains an essential read for anyone seeking a deeper understanding of the historic debate between liberal and orthodox Christianity.
