What is the primary purpose of soteriology?

The primary purpose of soteriology is to understand and articulate biblical truths about salvation. This branch of theology is focused on the study of how salvation is achieved according to Christian beliefs, encompassing the doctrines of grace, redemption, justification, and sanctification. It delves into questions like what salvation means, how it is obtained, and its implications for believers.

In contrast, promoting religious rituals and traditions pertains more to liturgical studies rather than soteriology, as this branch focuses primarily on the practices within worship rather than the theological aspects of salvation itself. Discussing moral philosophies relates to ethics and does not specifically address the salvific themes that soteriology covers. Establishing church governance falls under ecclesiology, which deals with the structure and authority of the church rather than concepts of salvation. Therefore, understanding salvation as articulated in scripture is the core focus of soteriology, making it the correct answer.
