Fact remains a baby shower is not a celebration of how the child is conceived...so therefore your stance is faulty.I guess you are having a hard time reading today. Let me post it for you again:
With a married couple to woman becames with child through God's Grace and through His prescribed methods. That is something to celebrate.
Celebrating that someone is with child and that they became with way through God's prescribed methods, i.e. sex within marriage.
If you want to say that we should celebrate any person that becomes with child or obtains a child, then certainly you think we should celebrate when a woman is raped or a homosexual couple adopts a child or, heck, even if someone abducts a child. Doesn't the child abductor need essential supplies?!
