I have problems with the pledge -- as pledging blind loyalty to your country is bad.
I think pledging loyalty should be separate from the Holy Name Devotion.
There is nothing wrong pledging loyalty to a country that is free of corruption and has instruments to free it of corruption.
And I have no problems in PRAYING for my country -- especially bad countries such as China, Zimbabwe, Iran, etc., need prayer.
Finally, God does not promise us happiness in this life. To me, in the context of this pledge, happiness is almost a MASONIC or FREE MASON thing, and not a Christian thing.
From my perspective, having happiness might be sin or lead me into the state of sin.
I just have a problem with this pledge, and I have another problem with the pledge appearing as a prayer for people to use in a Daily Prayer Book...
