Introduction The Reformed Theology provides a unique view on the concept of sanctification. Based mostly on the ideas promoted by John Calvin, it places a very heavy emphasis on the importance of the Scripture (Leclerc, 2010). Therefore, reformed Theology views the notion of sanctification as a dual concept, namely, as the definition of Christ and the stage of spiritual development that can be achieved by following Jesus’s teachings (Sider, 2005). The described approach is rooted in the Reformed perspective on human life, in general, as the idea of following one’s core beliefs in every step that one takes. Strengths and Weaknesses The proposed perspective on sanctification has its advantages and disadvantages. On the one hand, the fact that the suggested interpretation does not provide a clear description of sanctification weakens the argument. On the other hand, the opportunity for an individual to introduce sanctification into one’s life using union with Christ offers greater flexibility and a more personal relationship with God. Authors: Evaluation The notion of sanctification as it is represented in Reformed Theology has been debated broadly in the Christian theological discourse due to the multiple complexities in its logic. Therefore, each of the authors does a very good job at disentangling the key points of the Reformed position on the theological discourse and especially the notion of sanctification. For instance, Dieter et al. (1996) rely on the crucial points of the reformed perspective quite accurately, whereas Leclerc (2010) provides a historical context, and Sider (2005) addresses some of the controversial aspects of the Reformed Theology. Reformed and Wesleyan Position: Comparison The Reformed Theology is often compared to the Wesleyan one for a good reason. The two communicate similar points, elevating the role of an individual in achieving the stage of sanctification (Dieter et al., 1996). However, unlike the Wesleyan Theology, which keeps the opportunity for salvation open for any individual, the reformed one suggests that, once the chance for salvation is gone, it cannot be regained (Sider, 2005). Doctrine of Holiness In what ways did early Holiness themes influence John Wesley? The concepts of Holiness and sanctification are central to the Wesleyan Doctrine, which is why the principles of holiness as a notion are likely to be found at the roots of Wesleyan Theology. Indeed, diving into the history of the Wesleyan philosophy, one will realize that its founder, John Wesley, relied heavily on the early Holiness themes in the development of his perspective. Namely, early Holiness themes related to the Methodist teachings, such as the role of social engagement of an individual as the path toward Holiness have shaped Wesley’s interpretation of Christianity and its ultimate goal. Similarly, the importance of cooperation in small groups, mutual accountability, and, ultimately, unity as the early Holiness themes defined the Wesleyan Theology to a significant extent. Namely, the specified notions were incorporated to establish social justice as the foundation for Wesleyan Theology (Snider, 2016). Thus, the Wesleyan framework has led to the interpre
