I have a protestant friend who was Catholic before the new mass. She said it was considered a mortal sin to receive the Eucharist in the hand at that time. (Question 1-Is this true?) She said that one she went to confession on day because the Eucharist got stuck on the top of her mouth, and she had to use her finger to pry it off. When she told the priest in confession, he was shocked and said he almost did not want to give her absolution.
She gave this as one of her reasons for leaving the church.
I have heard other stories such as this. For example, a priest would not let a woman enter the church because she was not wearing a hat. Or a woman, while walking to church, had a rain drop fall in her mouth, and the priest told her not to receive communion. (Question 2-Are these rules still in effect for the traditional mass?)
