Thus? I certainly don't see the error you do.
I see the difference between the Catholic and Protestant views as if two people are looking at the same seven-faceted diamond but from different facets. The one sees images in the diamond - himself, his forebears, saints, etc. - and thus sees that to honor those images is to honor the Light which illuminates them. His emphasis is on the images, the physical.
It is a pretty analogy but incorrect. We do not look to others instead of God. We are part of God's family both temporally and eternally. We believe in the communion of saints. Those who have gone before and those who are here now participate in that same family mystery together.
Perhaps to add to your analogy... if Jesus is the diamond, then Protestants are blinded by the light and fail to see the diamond...
I regret that you do not discern the diamond metaphor or the Spiritual error of exclusion concerning the Eucharist.
I cannot make it clearer, so thank you for the discussion. May God ever bless you and those you love.
