I’m watching live, and at the 3:28:30’ish mark, the Bishop is giving a sermon. He is wishing everyone happy Easter. So, I thought that although the Church ended Lent after the morning vigil, she did not yet Easter until Sunday. However it seems I was wrong, as he is wishing the people happy Easter. And the Church apparently did this for 1,650 years. Confusing for those of us raised on Bugnini.
Also a good explanation of how since the 4th century, the Easter vigil was moved to the daytime.
He is also explaining what a glorious Lenten gift it is to Jesus to fatigue ourselves by attending these long services (4+ hours by the time Holy Saturday ends).
