What reasons were given to justify the veneration of icons?

The veneration of icons was justified by theological arguments emphasizing that icons serve as Windows to the divine, allowing believers to connect with the spiritual realm. Proponents argued that since Christ took on human form, depicting Him and the saints in art is a way to honor their humanity and divinity. Additionally, icons were seen as educational tools for the illiterate, conveying biblical stories and religious teachings visually. This practice was defended against accusations of idolatry by asserting that the honor given to icons is not worship, which is due to God alone.
