Final answer:
It is true that from the first to sixth centuries, both pagan and Christian influences were strong. Paganism dominated early on, but Christianity's spread led to its establishment as the state religion in the fourth century. Over time, Christianity's influence grew as it intertwined with Roman culture and politics, yet pagan influences persisted.
Step-by-step explanation:
The assertion that from the first to sixth centuries, pagan and Christian influences were strong is true. During this period, the Roman Empire underwent significant religious and cultural transformations. Paganism was the predominant religious practice initially, with a multitude of gods and practices integral to Roman society.
Despite the rise of Christianity, pagan influences did not immediately disappear. The transition from polytheistic worship to Christianity was gradual and complex. As the new religion gained dominance, Christian influences became more pronounced, with the construction of churches and the Christianization of Roman institutions. Yet, it took about a century for the persistent believers in the old Roman gods to significantly wane.
