Context: The term καταρτισμός appears in the New Testament in the context of spiritual growth and maturity. It is notably found in Ephesians 4:12, where the Apostle Paul discusses the purpose of spiritual gifts within the church. The verse reads: "to equip the saints for works of ministry, to build up the body of Christ" (BSB). Here, καταρτισμός is translated as "equip," highlighting the role of church leaders in preparing believers for effective ministry and service.

The concept of καταρτισμός is integral to understanding the function of the church as a community where believers are nurtured and developed. It underscores the importance of teaching, discipleship, and the use of spiritual gifts to foster growth and unity within the body of Christ. The process of καταρτισμός involves not only the impartation of knowledge but also the practical application of that knowledge in service to others.

In a broader theological context, καταρτισμός can be seen as part of the sanctification process, where believers are progressively conformed to the image of Christ. This involves both individual and corporate dimensions, as each member of the church contributes to the edification and strengthening of the whole body.
