EWTN Catholic Q&A
Question from K on 01-23-2004:

Hello! 1) In our Catholic Church we honour Mary and worship God. Could you please explain what is the difference between houring and worshiping.

Answer by Matthew Bunson on 01-30-2004:

You ask about the differences between veneration and worship. The technical terms that are used seem appropriate for the explanation. The chief ones are dulia, hyperdulia, and latria. Dulia is a Greek term meaning the veneration or homage, different in nature and degree from that given to God, that is paid to the saints. It includes, for example, honoring the saints and seeking their intercession with God. Related to dulia is Hyperdulia, the special veneration accorded the Blessed Virgin Mary because of her unique role in the mystery of Redemption, her exceptional gifts of grace from God, and her pre eminence among the saints. Hyperdulia is not adoration; only God is adored. Such adoration reserved exclusively for God is termed latria, a Greek-rooted Latin term that refers to that form of praise and worship due to God alone. I hope this assists you.
