Saw it for the first time tonight in my parish church.
It is to put the focus on what Jesus did in His passion, to remember it.
I have no problems with differing Christian faiths and their liturgy. It’s like “why” to me ... He did it all and there’s no need to add to His sacrifice for us. When He said “It is finished” He was talking about the Law. The Law is no more. He laid out the only thing we had to do and that was: Love G-d with all you heart all your soul and your neighbor as yourself. On this hangs all the Law. That’s it. One thing. Period. Nothing else.
