No that is not what is being said. As Catholics, we believe in the ministerial priesthood. As such it is necessary to identify the priesthood from the laity particularly in liturgical matters. Of course, if one doesn't believe in the ministerial priesthood or the liturgy then naturally they don't have a vestment problem but develop issues with those who do. Conflating their understanding of necessity and importance with what is proper.
If protestants would embrace 1 Timothy 4:4 and cease their iconoclastic ways they might eventually understand.
And lest their be any confusion a priest may conduct the duties of his office, if necessary, even when he's not in vestments. The Eucharist is still confected, confessions can be heard and absolution given etc.
Your post #1153 ca just as easily be applied to the rcc!
For everything God created is good, and nothing is to be rejected if it is received with thanksgiving,
HUH?
