Grateful? I am not in agreement with that statement. Should we have the “freedom” to go and come as we choose? yes! Should we be able to be the person God has called us to be, without restriction, yes! But! Does freedom include dividing what Jesus began, “…my Church” (Mt 16:18)?
I am glad that you are grateful for your “freedom” to be Mormon, I am glad that Henry VIII found freedom in starting his own church, since the Catholic church would not allow his divorce. I am glad that Martin Luther had the freedom to break away from the Catholic Church, and then throw off parts of the Bible because they verified Catholic teaching, (Maccabees; purgatory). I am glad that you are grateful for the “freedom” to destroy the Church founded by Christ.I am glad that you grateful to all of these things. Because by your gratefulness, you are glad that Satan can continue to destroy the church founded by Christ.
We (Christians) are divided,!!! A friend of mine pointed out that new denominations, or non denominations, begin by the hundreds, just because they disagree with the denomination they broke from. This, my dear sister, is not cause to be grateful. We should be in tears because we are divided. We are divided which is the opposite of what Jesus prayed for " … may they be one as we are" (Jn 17:11)
I am a retired transit bus driver and at one point in my driving career I fought the company in trying to force me to drive a bus with planned parenthood ads on the side of the bus. When I began to search out “fellow” Christians to help with the fight, I found so called churches that “don’t have a problem with this” .: DONT’T HAVE A PROBLEM WITH ABORTION?? ( Through the grace of God I did win the “freedom” from having to drive the buses with the baby murder ads on them).
There are churches to that accommodate the sins of homosexuality, there are churches that accommodate divorce, there are churches that accommodate polygamy etc.

When you look at the reasons for the separations of churches it becomes an extreme selfishness of saying that “MY INTERPRETATION OF SCRIPTURE IS CORRECT”. One time I went to a church called “Living Hope”, with a friend. The minister would quote scripture passages to get a point across to his followers that had nothing to do with (and at times opposed) that which he was trying to teach. When he was questioned about misquoting scripture, his response was that it was his way of getting his (?) point across.
We do have freedoms here in America that I am grateful for, but just think what this world would be like if all Christians were one. If we could all stick together in the one body that Christ prayed for. Would we have seen 911? Would we have seen Oklahoma bombing, or guns in schools, or a president that does not acknowledge the National Day of prayer?
What you appreciate in “freedom” makes me sad.
