Final answer:
In Christian theology, after Christ subdues all things, he is subject to God the Father, which is also depicted symbolically in Christian art. The correct option is (a).
Step-by-step explanation:
When all things are subdued by Christ, he is subject unto God the Father. This understanding is rooted in Christian theology, which recognizes the trinity comprising God the Father, the Holy Spirit, and Jesus Christ.
In 1 Corinthians 15:27-28, it is stated that after Christ has put all things under his feet, he himself will also be subjected to God the Father, so that God may be all in all. This theological perspective places Christ in a position of completing his redemptive work and then submitting to the Father's ultimate authority.
Christian art, including Renaissance and Byzantine works, often illustrates these concepts. For example, Christ may be portrayed seated on an orb representing the Earth or the universe with angels by his side, symbolizing his triumph and divine authority.
Moreover, Mary is sometimes depicted as the Throne of Wisdom with Christ on her lap, showing her role as both mother and as a symbol of the Church itself.
These artistic interpretations are visual representations of Christ's role as judge and savior, as well as the intimate relationship between the divine figures of Christian belief.
