Nicaea II, also known as the Second Council of Nicaea, was an ecumenical council held in 787 AD that primarily addressed the issue of iconoclasm, which was the rejection or destruction of religious images. The council reaffirmed the veneration of icons and established a clear stance against those who opposed their use in Eastern Orthodox worship. This council marked a significant moment in Eastern Orthodox theology as it sought to define the role of icons within the faith, asserting their importance as a means of connecting the faithful to the divine.
