New Spanish Editions of C.S. Lewis Classics Bring Timeless Christian Apologetics to Latin America


Grupo Nelson has released newly updated Spanish editions of two of C.S. Lewis's most celebrated works, Mere Christianity and The Screwtape Letters, specifically designed for Latin American readers.

The editions, which launched in February 2026, feature modernized language aimed at removing barriers created by older, archaic translations while preserving Lewis's original theological message.

Juan Tomás Widow, president of the Faith, Art and Myth Association, collaborated on the project. He emphasized the enduring relevance of Lewis for today's believers.

In times of confusion, returning to Mere Christianity is like recovering our compass.

The initiative seeks to introduce Lewis's intellectual and spiritual legacy to new generations across Latin America. Rather than presenting him as a historical figure, the project positions Lewis as a continuing voice for reasoned faith.

A key goal of the collaboration between Grupo Nelson and the Faith, Art and Myth Association is to encourage intellectual dialogue in schools and universities throughout the region.

Lewis (1898 to 1963) was one of the most influential Christian intellectuals of the 20th century. He taught at both Oxford and Cambridge universities and authored more than thirty books spanning literary criticism, children's literature, fantasy, and theology.

His works have maintained broad readership appeal across generations, and these updated editions represent a renewed opportunity for Spanish speaking evangelical readers to engage with his foundational apologetics.

The updated editions aim to make Lewis's arguments accessible to contemporary readers without diluting their theological depth. By updating phrasing that may have been unclear or outdated in previous translations, Grupo Nelson ensures that the core message of the Gospel remains front and center for millions of Spanish speaking Christians.


The Crusader's Opinion

C.S. Lewis once said that Christianity, if false, is of no importance, and if true, is of infinite importance. The only thing it cannot be is moderately important. Latin America is home to hundreds of millions of Christians, and giving them access to one of the greatest defenders of the faith in clear, modern language is not just a publishing decision. It is an act of spiritual warfare. The enemy would love nothing more than for Lewis's razor sharp dismantling of atheism and moral relativism to gather dust on shelves, incomprehensible behind outdated translations. Grupo Nelson just made sure that will not happen. Every young believer in Bogotá, Buenos Aires, and Mexico City now has a weapon of truth in their hands.
