why is Jesus portrayed as such a handsome person? Not that it is bad, but it is not the truth.
Beauty is in the eye of the beholder, and true beauty involves the soul.
As for the externals, are you taking into consideration the transformation that took place after His glorification?
when you kneel down and pray in front of a random picture, aren’t you engaging in idolatry?
Idolatry consists in divinizing what is not God. Man commits idolatry whenever he honors and reveres a creature in place of God (CCC 2113).
Christian iconography expresses in images the same Gospel message that Scripture communicates by words. Image and word illuminate each other. (CCC 1160).
This issue came up, was discussed extensively, and was resolved in 787 AD at the Seventh Council of Nicaea.
The veneration of icons (of Christ, but also of the Mother of God, the angels, and all the saints) is not contrary to the first commandment which proscribes idols.
“The honor rendered to an image passes to its prototype,” and “whoever venerates an image venerates the person portrayed in it.”
The honor paid to sacred images is a “respectful veneration,” not the adoration due to God alone: religious worship is not directed to images in themselves, considered as mere things, but under their distinctive aspect as images leading us on to God incarnate. The movement toward the image does not terminate in it as image, but tends toward that whose image it is. (CCC 2131-2132)
