Interesting discussion. I came from the Anglican Church before becoming Catholic so I still somewhat stay in contact with my former pastor, who seems to be insulted by Rome, as he says Rome thinks they are the only Church that exists lol.
What does it all mean from a Catholic perspective? Any Catholic can take a stab at it here.
I think the orders are not valid, of course, as they broke from the barque of Peter and therefore their Church does not contain the promises of Matthew 16. But that doesn’t mean the Anglicans and Lutherans don’t count as I see some here seem to imply.
So Protestants lack any tangible authority. But I think they are fine with that and believe too much power corrupts, anyhow.
They also lack a valid Eucharist. This is a bigger deal. Most don’t really believe in it anyhow. However, if Catholic/Orthodox synergistic soteriology is correct, then lacking a valid Eucharist could be the difference between 2 years in purgatory vs 200 years.
So yeah, I guess invalid orders do matter. With that said, I wish the “you don’t count” implication from us could be put to a halt, somehow, when we discuss this issue.
