I am a Catholic, and when I took my first Holy Communion in the 1960s, the priest placed the wafer straight onto your tongue. I was quite happy with that. Later, the priest used to place it on your hand and you placed it on your tongue yourself. When I was quite young still, a schoolmate dropped her wafer on the floor. There was a huge hullabaloo. The place she dropped it had to be cordoned off and blessed and all kinds of things. I am left handed and very clumsy so I was terrified of that happening to me. I chose to have it on the tongue after that. Even if the priest was reluctant, I just stuck my tongue out. And we never ever ever got to drink wine. Ever.
Now, of course, being divorced, I am no longer allowed to take communion (and I no longer go to church), but I thought this was interesting. How times have changed!
