I've heard that the Our lady of Guadalupe image despite being a western Icon, is acceptable in Orthodoxy. I've even heard that the image was accepted by the Orthodox accepted the image before Rome. Is this true? and can I venerate it?
You should be asking yourself why you feel so compelled to want to venerate it in the first place. Are there not enough venerable Orthodox icons for you to venerate that you must resort to Latin ones?
No, you should not venerate it.
I never felt the need to venerate the icon, I heard that it was accepted as a valid Icon by the Orthodox in the 16th century. I just wanted to check if this was true or if it was ecumenism.
