Craziest thing from a Catholic…
The head of the Baptism Instruction Team at my husbands Church. Hands down…
Long Story short…
I was pregnant with my 1st, and shopping at our local grocery store, I was stocking up on formula when a lady, with a really bright red purse, comes up to me, and literally goes BALISTIC about not even trying to breast feed, and how horrible formula was, and how I was lazy to not even try to breast feed. When she finally stopped to take a breath…I looked at her and calmly explained I had a medical condition that required medication that would make my breast milk unsafe, and walked off.
Flash forward to a month and a half after our first was born. We went to my husband’s parrish for the first time. A woman approaches us gushing over our daughter, and telling us that she looked forward to seeing us in the Baptism classes, I explained that I was Lutheran and the kids were being baptizede Lutheran. She smiled and said “That’s wonderful, close enough” and preceded to talk about how kids were such a blessing. I kept looking at her trying to figure out where I knew her from, her husband walked up and said she had left her purse in the pew, and then it hit me…It was the Lady with the red purse from the grocery store.
I laughed all the way home, my husband was a little embarassed (he had gotten a little bit of a lecture from the priest about our kids not being raised Catholic). I just found it humorus that the leader of the Baptism Classes felt that Lutheranism was close enough to Catholicism to be OK, but Formula was poison compared to breast milk.
Other things I’ve heard…Lutheranism is like Catholic Light.

Lutherans don’t baptise kids
Lutherans don’t believe in the real presence
I’ve been called a heretic…That one’s not really funny
Mainly mixing up protestant faiths and believes.
