Statues are not windows into heavan but give physical form to what they depict. In contrast, icons do not give form to what they depict because it is just painted on and is only in two dimensions. When you pray to a statue you are praying to an image that has form, that is an object. Can you make a statue into a window? Can you take glass, heat it, and then mould it into a 3D image and be a window? You would not be able to see at all clear the other side b/c the light waves would bend as they hit a surface that is not even. Therefore, your attention is on this statue itself b/c you can not see beyond it.
Roman, in the days of the early church all paintings were two dimensional...had been that way since the Egyptians, maybe even before... While we look at them now as 'just an image' without form... that is how all paintings were then... Catholics don't pray to a statue... they kneel, bow their head, and pray for assistance from the saint it represents.
I have been in RC churches with both statues and icons, they are both used the same way.. . there are some Christian faiths who look at icons as you are looking at statues.. And some people think kissing an icon is the epitome of image worship... but we say otherwise....they see any representation as image worship.. whether 2 or 3 dimensional... And if you look at the fans carried in church, many have 3 D icon reliefs on them... they are not 2 dimensional engravings of icons.... so , I say, let us not judge what the Catholics use to pray... unless we can see inside their hearts and spirits... which we can't...
