Abstract
The peculiarity of any social teaching, Catholic, Protestant or otherwise, is that it is an unsteady marriage between the dogmatically permanent beliefs and the perennially changing historical contexts. Any authentic and relevant social teaching needs to mirror a two-fold fidelity: Faithfulness to the universal truths to which the social teaching is a reflection, and loyalty to the historical contexts to which the social teaching is inextricably embedded. The merit of Cartagenas’s book Unlocking the church’s best kept secret is that it epitomizes the wobbly balancing act that takes cognizance of this two-fold fidelity.
