Let me substitute Jesus for Mary in the prayer and you tell me if it doesn't fit Him better...
***O blessed Son of God, in that we set our hope on thee Jesus, may we not go astray; but through thee Jesus may we be delivered from all adversities, for thou Jesus art the salvation of all Christian people.***
That... is my point.
And you would have us ignore the countless examples of the Light of Christ shining through His creations as we pray for It to shine through us.
Each and every saint that we commemorate is an example that His Light can shine through us. When we celebrate them, we celebrate Him first and foremost. But that doesn't fit the interpretation of others and so they accuse us of blasphemy.
I contend that there is no blasphemy in our hearts, our minds, or our practices.
And that is my point.
