Final answer:
Option (c), The first five centuries of Christian history experienced significant change in the practice and development of the sacraments, reflecting major transformations within the Church and its influence on spiritual life.
Step-by-step explanation:
The first five centuries of Christian history were marked by significant change in the practice of the sacraments. During this period, Christianity went through considerable transformation, adapting to changes in population size, cultures, and converting new members.
From the simple domestic architecture of early Christian communities to the grandiose churches post-Constantinian era, there was a clear evolution in religious practice and the administration of sacraments.
The notion of spiritual salvation was intertwined heavily with the sacraments, administered exclusively by the clergy, signifying the Church's hold on spiritual life. Moreover, events like the Protestant Reformation in the 16th century exemplify the dramatic changes and challenges that occurred within the Church, leading to diverse Christian doctrines and practices.
