As a Christian, it's not good to be praying for objects that makes it them seem like idols
A very strong remark. I wonder how the holy fathers would comment on this, that icons and crosses are akin to idols.
They are not idols. It is a reminder of sort. For example, if you look on icon and pray, you are not praying to icon, but to that saint on icon for protection. And crosses are same thing, it remind us of wrong deed that is done to Jesus, and suffering that he went true. Most of items that are used by religious people have meaning, and gives them some meaning, but they are not idols.
