I was drawn to this miracle of Our Lady's image not made by hands even before I was Catholic or Eastern Orthodox. I was at the house of the pastor I worked with at an Assembly of God and he had on EWTN (this was in 1994). They were discussing the icon and it's symbolism. Pastor Dan made the comment, "It reminds me of the woman clothed with the sun in Revelation."
My next experience with OLG occured while I was in the hospital for asthma during Lent 2006. Bob & Penny Lord were on EWTN with a program about her and Juan Diego. Hearing the whole story for the first time brought me closer to Mary's visit to America.
In closing, I'll leave you with the Byzantine Catholic Troparion and Kontakion for the feast of the Theotokos of Guadalupe:
When you appeared in the New World, O Theotokos, you fixed your image on Juan Diego's rose laden tilma. All the poor, hungry, and oppressed seek you, Lady of Guadalupe. We gaze upon your miraculous icon and find hope, crying out to your Son concealed in your womb: Hear our plea for justice, O most merciful Lord.
