Can Logic Prove Christianity? Joshua Sijuwade v Amos Wollen hosted By John Nelson

In this episode of Unbelievable?, host John Nelson is joined by philosophers Amos Wallen (Oxford) and Dr. Joshua Sijuwade to debate whether Christianity can be supported by a priori reasoning — arguments based purely on logic rather than historical evidence.

Dr. Sijuwade argues that philosophical reflection on God’s nature may lead to surprising conclusions, including the incarnation and even the Trinity. Drawing on ideas from thinkers like Richard Swinburne, he explores whether concepts such as perfect goodness, omniscience and divine love logically point toward core Christian doctrines.

But Amos Wallen is sceptical. Do these arguments really increase the probability of Christianity — or do they simply show that some form of incarnation is possible? And can philosophical theories of love, divine knowledge, and omnisubjectivity really lead us all the way to the Father, Son and Holy Spirit?

Along the way, the conversation tackles big questions:

• Can philosophy establish an incarnation without history?
• Does God need a body to fully understand human experience?
• Can perfect love logically require multiple divine persons?
• And if the Trinity follows from love… why stop at three?

This wide-ranging philosophical exchange dives deep into reason, theology and metaphysics, asking whether pure logic can take us all the way to Christianity — or whether faith ultimately needs something more.
