aries, You are right. I read a story about a cong. that hired a chazan who brought along his own choir for Rosh Hasanah/Yom Kipur and it turned out that one of them was not jewish and the cong. refused to pay. It went to court and the judge asked the cong. to prove there is an halachic ishue with a non jew who was not the actual chazan but part of the choir. So they turned to one of the gedolim who told them that since tefilah is in place of korbanos it has the same halachah. A none jew was not alowed to even enter the beis hamikdash. My point is that if we wouldn’t learn hilchos korbanos how would we be able to draw a paralal for tefilah.
