Conference Theme: Deconstructing in Faith
In recent decades, many have left Christianity—some of our friends and family—describing it as a “faith deconstruction.” This conference provides an opportunity to understand and help those experiencing disenchantment with Christianity. Furthermore, there is an unfortunate lack of critical self-awareness of the underlying assumptions from which this deconstruction process takes place. So, this conference will also provide the opportunity to “deconstruct” the deconstruction process (cf. 2 Cor 10:4-5).
