That's merely the opinion of those who set their own sola ecclesia over and above even the received Word of God, which is part of what gets the more liberal among the Methodists (and others too) in trouble.
How do we know they are wrong?
Those here who are not Roman Catholics, know that the individuals and activities which are being discussed are wrong, not by consulting with the Roman Catholic Church, but by consulting with (and understanding well enough) the Holy Writ.
Otherwise, if this were not true, you wouldn't be able to be operating under the assumption that many here agreed that praying over an abortion clinic to "bless" it, was ill-advised, at best.
It helps to have that opened to one's own understanding by the Holy Ghost --- to have he Lord be present, and then to also search Him out.
As it is written;
Acknowledge Him in all your ways, and He shall direct your paths.
Notice the above passage predates the inception of the Church of Rome.
So?
The Holy Scriptures still refute them, and their 'feelings'.
No, the final arbiter is the Lord Himself --- not the RCC, by any stretch. When they (the RCC) too chooses to have departed from the Word, then they too are found in error, eventually, if not sooner.
I can point to paces where the RCC has made such departures, overturning even their own earlier traditions, and have done so more than once, previously, on this forum. Singular 'papacy' as that came to be known of among the RCC, is one of those departures from prior tradition and NT Scriptures both.
It's that very stretching and conflating which brings about yet other errors, albeit arguably, apparently enough not presently inclusive of attempt to openly pray blessing over an abortion facility, save perhaps on lowest levels somewhere, and lacking the backing of the rest of the church --- sort-of like this activity under discussion lacks the support of significantly wide swaths of Methodists themselves.
You were beater off when you discontinued the conversation.
