Well, if we are talking about Protestantism, then very little.
What are you, nuts??? Every Protestant church I've been in follows Justin's take on it...
What is telling in Justin's remarks is that there is no one waving incense smoke around...No one is participating in a Catholic Eucharist celebration...Mary isn't mentioned at all...Nothing going on with altar boys...Nothing at all is Catholic in Justin Martyr's church service...
And interesting quote from the link you posted...
It is to Saint Ignatius the God-bearer that we owe most of the information that we have, regarding the significance of the Bishop in the early Church.
Since Ignatius' information is known to be forged, your religion has nothing in the way of the significance of any bishops, anywhere or at any time...
Thanks. I have had the same experiences over my lifetime in the different churches I have gone too.
Except that they are.
