"A Treatise of the Cohabitacyon of the Faithfull with the Unfaithfull" by Vermigli et al. is a religious treatise written in the mid-16th century. This work examines the complexities involved in the coexistence of faithful Christians with non-believers and heretics, including discussions surrounding the appropriateness of interacting with those who hold differing or erroneous beliefs. The text is rooted in Christian doctrine and aims to provide guidance on how to navigate these relationships responsibly. The opening of the treatise introduces several key themes concerning cohabitation and interaction between the faithful and the unfaithful. The text begins by presenting the central question of whether it is lawful for the faithful to engage in familiar conversations and cohabit with the unfaithful. It outlines the perspective that Christians should refrain from participating in practices deemed idolatrous or superstitious, such as attending popish masses. Throughout this section, Vermigli provides scriptural references, theological reasoning, and examples from biblical history to argue that while some degree of interaction may be permissible, it must always safeguard the sanctity of faith and not be a stumbling block to moral integrity.
