The Son is the image of the invisible God (Colossians 1:5) and the radiance of God's glory and the exact image of God's nature (Hebrew 1:3), so while we can't see invisible traits like like righteousness, holiness, goodness, justice, mercy, faithfulness, love, joy, peace, kindness, gentleness, self-control, the Son is the personification of those traits in the form of a body that we can see expressed through living in sinless obedience to God's word, or in other words, he is God's word made flesh and he is who we see when we look at the Father. The problem with idolatry is that it misrepresents the nature of God, so if the Son were anything less than the exact image of God's nature, then worshiping him as God would have been idolatry. The way to worship the Father is through partaking in the divine nature by expressing His traits, which means that the way to worship the Father is identical to the way to worship the Son. For example, doing charity is a way to worship both the Father and the Son.
