Grace and Peace,
It would appear that many, or some, Early Church Fathers were against images of our Lord, etc. Why are we so sure we are right about this practice?
Graven images in the OT was meant to refer to statues of pagan gods.
Since Christ Jesus became Man and we know that He was true man and True God, His image cannot be considered graven.
Tradition has St. Luke the Evangelist writing the first Icon of the Theotokos and the infant Christ.
In more practical terms, one has photos of his family either in his house of in his wallet. We all know that the picture is not the person but represents the person. When we pull out the photo dont we say that "this is my son, or daughter?" We know that the picture isnt the actual person but is a representation of the person we all love.
We dont venerate the physical Icon we venerate who the Icon represents after all the Icon is nothing more than wood, egg pigment and gold leaf. One doesnt venerate the elements that make up the icon but the one who is depicted.
