Question - What is the message of this Rashi for us in our generation?
Vayikra, Chapter 48
רעיא מהימנא פִּקּוּדָא דָּא לְהָבִיא קָרְבָּן עַל סַנְהֶדְּרֵי גְּדוֹלָה שֶׁטָעוּ, תָּנָאִין ואֲמוֹרָאִין ע' סַנְהֶדְּרֵי גְּדוֹלָה הָיוּ, וּמֹשֶׁה עָלַיְיהוּ. וְע' סַנְהֶדְּרֵי קְטַנָּה הֲווֹ, ואַהֲרֹן עָלַיְיהוּ. וּבְגִין דָּא אָמְרוּ מָארֵי מַתְנִיתִין, מֹשֶׁה שׁוּשְׁבִינָא דְּמַלְכָּא הֲוָה, וְדָא תִּפְאֶרֶת, מִתַּמָּן סַנְהֶדְּרֵי גְּדוֹלָה. אַהֲרֹן שׁוּשְׁבִינָא דְּמַטְרוֹנִיתָא, וְדָא מַלְכוּת, הֵ"א זְעֵירָא קָרֵינָן לֵיהּ, כְּגוֹן (בראשית כ״ט:י״ח) אֶעֱבָדְךָ שֶׁבַע שָׁנִים בְּרָחֵל בִּתְּךָ הַקְּטַנָּה. וְעַל שְׁמָהּ אִתְקְרֵי סַנְהֶדְּרֵי קְטַנָּה.
The job of Moshe Rabbeinu is to escort Hashem to the Chuppah. He is the "best man" so to speak of the Chasan. The job of the Kohen is to escort us, the Kallah, to the Chuppah.
Tosher Rebbe - the job of the Kohen is to ensure that we don't become יִטַּמָּ֖א בְּעַמָּֽיו - mixed up among the nations of the world.
מִכְּדֵי רַב בְּיִשְׂרָאֵל קְרָא, מַאי טַעְמָא חֲתַם וְלָא בָּרֵיךְ? לָאו מִשּׁוּם דְּבָעֵי לְמִיקְרֵי אַחֲרִינָא בָּתְרֵיהּ? לָא, רַב בְּכָהֲנֵי קְרָא. דְּהָא רַב הוּנָא קָרֵי בְּכָהֲנֵי.
The Gemara attempts to clarify the halakha based upon Rav’s conduct. Now, Rav must have read the portion that is designated for an Israelite, as he was neither a priest nor a Levite, and therefore he was the third person to read from the Torah. What, then, is the reason that when he concluded his reading he did not recite a blessing? Was it not because another person was to read after him, and since only the last reader recites a blessing, Rav did not recite a blessing upon completion of his portion? This would indicate that four readers are called to the Torah on public fasts. The Gemara rejects this proof: No, Rav read the first reading, which is generally designated for priests. He was the leading Torah authority of his generation, and one who holds this position is called to read from the Torah even before a priest, as Rav Huna would read the first reading, which is generally designated for priests, and Rav would do the same.
The Tzaddikim are the Kohanim of the generation.
Tiferes Shlomo -
Question - If he is bad towards people, how is he a Tzaddik?
Answer: He is righteous but he lives only for his own service of Hashem and does not work to help others achieve their greatness.
Rav Moshe Weinberger: Those Jews who are still among the nation - ie. there are people who are telling them that they are wanted among the nation and bringing them back from assimilation - the Kohen is less accountable for them.
But when a Jew is alone, when he is "Meis Mitzvah" and there are no other Jews to tell him that he is a valued member of the Jewish people - the Kohen must become Tamei in order to take care of his needs.
