The correct answer is C) to take the worshipper into a more spiritual mindset and instruct on biblical themes.
The purpose of church mosaics is to take the worshipper into a more spiritual mindset and instruct on biblical themes.
More than an aesthetic instrument that embellished churches, the use of mosaics helped the followers to get deep in their prayer moments and have the mindset to understand the meaning of the doctrine taught in the bible. Church mosaics were popular during the Byzantine empire. They were created as an artistic expression to represent passages in the life of Jesus or to describe moments of the teachings in the bible.
