there seem to be a lot of rules here that make xthing ok for Catholics but not ok for Protestants. On one level you my superficially make yourselves look good, but on the other you aren’t making people want to join you.
Syele;
Unity should be unity of doctrine. Not unity of Liturgy (we have 7 churches and 13 Rites and I Use-Anglican-in the Catholic Church) or of discipline (married and unmarried priests; unmarried Patriarchs; unmarried Bishops).
Many Catholics ( I work with them!) think ‘Roman Catholic Church’ is the name of the worldwide Church. Many do not know that the original language of our Liturgy was koine Greek (hence the fossil in the Roman Rite of the ‘Kyrie’)
Or that the Bible was translated 8 times into Old and Middle German BEFORE Luther came along and wanted to ax Revelations and most of the Letters in ‘his’ Bible.
That is the Unity I am writing of: not small, of no consequence, things about how Grace is given or received.
The fools fight over those things (and our Church has had a history of fools in spades, after all, we are a Church of sinners) and have down evil in their version of what constitutes Christianity.
As to differences: we have them in our Orders and in our Rites.
But they are NOT differences of DOGMA or DOCTRINE.
In other words, you will be hard pressed to find a Catholic who
is a Symbolic communion/age of reason baptising/predestination/it’s just an ordinance not a ‘sacrament’ believer.
Protestant denominations have these doctrines and some have taken the Catholic view on a few of them.
That is where Unity is under stress, but it is the Grace of God (regardless of the scholastic view) that keeps us Whole.
