Final answer:
The statement is false. Ministry is not exclusive to professional clergy, as lay members often serve in various capacities within the church, embodying the concept of the 'priesthood of all believers'. Every baptized believer can be considered part of the church's ministry.
Step-by-step explanation:
The statement that ministry is only for professional clergy and not for lay members is false. Throughout history, there has been a notable distinction between clerical roles within the church. The clergy was divided into secular clergy, who lived in the world, and regular clergy, who lived under a religious rule and were usually monks. However, in terms of ministry and service, every person can have a role, and this has been recognized in various religious contexts. Lay members often have an essential role in the church's ministry, serving in various capacities that do not require ordination.
In Christian theology, it is commonly understood that all baptized believers are part of the 'priesthood of all believers', which means that ministry is not reserved only for those who have received professional clerical status. Also, considering the diverse roles that lay members can hold, from serving in the ministry of the church to being active in community service and charitable works, the ministry is far from being exclusive to the clergy. The idea that lay members also participate in ministry reflects a more inclusive understanding of Christian service.
