Does the congregation say "am kedoshecha ka'amur" before birchas kohanim?

Question

Does the congregation say "am kedoshecha ka'amur" before birchas kohanim? Or only the chazzan?

Answer 1

In the Shulchan Aruch in Orach Chaim 128:10 the Remo says וחוזר ואומר עַם קְדוֹשֶׁךָ כָּאָמוּר בלחש, i.e. that the Chazzan says it quietly.

The Mishna Brura (ibid 27) says that the Chazzan says עַם קְדוֹשֶׁךָ, and he adds that those locations where the Cohanim say it, are mistaken.

לו: וחוזר ואומר עם קדושך - היינו הש"ץ ומה שנוהגין באיזה מקומות שהכהנים אומרין עם קדושך טעות הוא:‏

That said, I've been in many a shul where the congregation said עַם קְדוֹשֶׁךָ כָּאָמוּר out loud, and the officiating Rabbi never objected.
