In Orthodoxy they are worshiping Father (God), Mother (Mary) and Son (Jesus).
Both Orthodoxy and Catholicism are trinitiarian, and worship the Triune God: the Father, the Son and the Holy Spirit.
Mary is not divine; whe is the first among saints. Her unique service is to give birth to our Savior. For that she is venerated, that is honored as a human being and a saint.
Note that venerating relics of saints is entirely scriptural (Acts 19:12)
You both sound as either Atheists or Protestants, people who do not understand authentic Christianity but like to express their ignorant opinions of it.
By kissing a belt that may or MAY NOT BE from Mary??? I think it lines up more with superstition
Please don't bear false witness against the Orthodox. They do not "worship" Mary, only the Father, Son, and Holy Spirit.
Anyone alleging otherwise is bearing false witness and judging the faith of their brother.
