Step-by-step explanation:
The phrase "sancta ecclesia" translates to "Holy Church" in English, so the correct answer is C) Church. The term 'ecclesia' has its roots in ancient Greek and referred to a political assembly of citizens, but in a modern religious context, it generally refers to a congregation or the church. The Christian doctrine, influenced by Catholic traditions and creeds like the Nicene Creed, uses terms such as sancta ecclesia to emphasize the holiness and spiritual authority of the Church. Different denominations of Christianity, including Catholics and Protestants, interpret sacred texts like the Bible and the Apocrypha differently, which affects their respective doctrines and practices, but the fundamental belief in the 'Holy Church'—sancta ecclesia—remains central.
