My friend Sarah was raised a Baptist. Her mother was a Catholic who fell from the faith due to terrible misunderstandings, and now her daughter has been lost.
The daughter fell to the brink of atheism for a while, and now she has trouble growing in any faith at all. She still clings to what she understands of the Baptist tradition, but I believe it is being destructive toward her recovery (especially since I am her only religious friend, and am thoroughly not Baptist… oil and water, I swear).
I have given up any aggressive pursuit of her conversion or deepening her understanding of Catholicism, so I rely now on prayer (silly of me, though… I should have done this in the first place).
Please, pray for them and their family. Pray that the scales on their eyes be removed by His love, and allow them to see the Truth that the Catholic Church has been charged with protecting.
