Question: What is the Chidush? It says "v'Kidashto" - for every matter of Kedushah, to bless first!

Answer: We do not mean literally equal. Rather, it means that also the Kohen is a Chacham, just he is not as important as R. Freida. Even so, R. Freida did not want to read before him.

Explanation #1: We must say that other Kohanim were submissive to R. Freida. If not, there was no Chidush [that he never read first];

We find in Gitin (59b), that Rav Huna would not have read [first] in place of a Kohen if not that R. Ami and R. Asi, the esteemed Kohanim of Eretz Yisrael, were submissive to him.

Explanation #2: Alternatively, we can say that Rav Huna read like a Kohen only because [all] the Kohanim were submissive to him, i.e. only on Shabbos and Yom Tov, when there is a multitude [in the Beis ha'Keneses];

However, on Monday and Thursday, he (a bigger Chacham) may read [first] even if he is not so great (that all Kohanim are submissive to him).

Support: In Gitin, it is clear that we distinguish like this.

R. Freida did not want to read before a Kohen even on Monday and Thursday.

Explanation #3 (Rashi): Here, we discuss Birkas ha'Mazon.

Support: It says "I did not bless." It does not say "I did not read";

There was no enactment [that a Kohen must always bless] due to Darchei Shalom. Even so, R. Freida did not want to bless before a Kohen.

Explanation: This was even in a way that he (Avuha or Minyamin bar Ihi) could not come to an oath, and even if an oath will be incumbent on the Nochri, he would exempt him from it;

This is permitted for other people. Even so, he did not want to make [a partnership with a Nochri].

Question: Why does it say "further"? Above he was more lenient than Chachamim, and here he is stringent. If so, why does it say "further"?

Answer: "Further" refers to what R. Yehudah said in the Reisha, we may sell it for a Chatzer. He permits only for a Chatzer, but Stam, it may not descend from its Kedushah;

R. Yehudah said further, i.e. another stringency, in addition to the first one.

Implied question: In Pesachim (101a), we say that guests eat and drink in the Beis ha'Keneses!

Answer: It means that they eat and drink in the room next to the Beis ha'Keneses.

Explanation: As long as they are Batel [they have no Kedushah].

Proof: We see in the Beraisa above, and also the Amora'im, did not want to enter them while it was raining to avoid the rain, only because learning requires clarity [and they could not think clearly in the rain].

Here we discuss after they were destroyed. Then, the stipulation helps.

Distinction: The Tenai helps only for those in Bavel. When the redemption will come, soon in our days, their Kedushah will be uprooted;

The Tenai does not help only for those in Eretz Yisrael. Their Kedushah is permanent.

Question: Since a Tenai helps for those in Bavel, it is difficult above (26b)! Ravina had a [destroyed] Beis ha'Keneses in his land. Rav Ashi told him to buy it from the seven governors of the city;

Why was this necessary, after it was destroyed?

Answer: It is because he seeded it. Seeding is overly frivolous, and agonizing. Therefore, it is forbidden even after it was destroyed [unless it is sold through the seven governors of the city].

Explanation: This is when they are built. After they are destroyed, everything is permitted.

We need to hear this, because one might have thought that only eating and drinking, which are overly frivolous, are forbidden;

However, calculations, which are not so frivolous, one might have thought that they are permitted. [R. Asi] teaches that this is not so.

Implied question: In Nidah (40a) we say that even like a mustard seed [or even less] is Tamei! (Why do we call this a stringency of Benos Yisrael?)

Answer: Perhaps there we do not require seven clean days [for less than a mustard seed], but she becomes Nidah mid'Oraisa.

Question: Where do we find that a drop like a mustard seed obligates seven clean days mid'Oraisa? Surely, Chachamim did not make a decree unlike anything in Torah!

Answer: We find this regarding a drop on her seventh clean day. It destroys her entire count [and obligates counting another seven clean days].
