Final answer:
Martin Luther's writing suggests that all Christians have equal access to spiritual authority and can perform ecclesiastical functions, implying a broader principle of shared community roles that could align with being a jack-of-all-trades.
Step-by-step explanation:
Based on the writings attributed to Martin Luther, the concept of whether a person should or can be a jack-of-all-trades is not directly addressed; however, one can infer that Luther's perspective on the priesthood of all believers suggests an egalitarian notion that could extend to the idea of trades and vocations. According to Luther, all Christians, by virtue of their faith and baptism, share in the spiritual priesthood, blurring the lines between the sacred offices and the laity. Thus, he advocates for the universal priesthood and authority of believers to discern and interpret the Scriptures, implying that in spiritual matters, no one is restricted to a single role or function, much like the concept of being versatile or multi-skilled in various trades. Luther also critiques the hierarchy within the Church, particularly the position of the Pope, pointing out that all believers have equal standing in the eyes of God and should serve the community based on mutual consent, not inherited or ordained status. While Luther's arguments are primarily theological, they suggest a broader principle of community and shared responsibility that could lend itself to the notion of versatility and adaptability in various trades and skills.
