I know for what I went through as a young person, our first Mass on Sunday was 6am or 6:30am. So, that would be a 6 hour fast. I try to follow this. It is with the understanding that Christ was the first to be consumed before water or food. If you need medication you are allowed to do so and receive Christ.
To me, this is apart of the belief that Christ is truly present. This is disappearing and that is how the enemy works. No communion rail, no kneeling, tabernacle no longer, no more genuflecting, followed by how we dress, and no more veils and you could go on. Very Demonic.
