Kol Yisrael Bnei Malachim Hem

Shtait in the last Mishna in the 14th Perek of Shabbos that we cannot apply a certain type of oil on Shabbos since it is usually used for a medicine, but Bnei Malachim can use it on Shabbos because they regularly use it as a bath. A Tanna then comments that we can all use it because "Kol Yisrael Bnei Malachim Hem."
Such a comment is not unique to Chazal - a congruent comment exists by Heseiba on Pesach where the Gemara says that Women don't require Heseiba but a Chashuv women does. The Ba'al HaTurim in quoting that Halacha says "Kol Hanashim Shelano Chashuvot Hem."
More so by the case in Shabbos, I wonder about the Halachic motivation of the authors of such statements. In the Pesachim example, perhaps, nowadays all women are chashuv which warrants requiring Heseiba, however, in the Shabbos example, how are we to understand that only "Kol Yisrael" are now Bnei Malachim? If the Tanna had stated that everyone now is Bnei Malachim, as the Tur did, then I would take the statement at face value. But are we to assume that only Yisrael now use that oil as a bath and the Umos Ha'Olam do not?
It is clear that the Tanna has something besides the topical Halachic implications in mind by stating "Kol Yisrael" instead of "Kulanu."

Rosh Chodesh vs. Chol Hamoed

On Chol Hamoed, those of us who wear Tefillin, remove them before Hallel since Hallel belongs to the Moed portion of the day and Tefillin belong to the Chol portion of the day. Why then, on Rosh Chodesh, does everyone leave their Tefillin on for Hallel and only remove them before Mussaf?

Kriat Shma vs. Shmoneh Esrei II

In one of his shiurim on Parshat Tazria (although I'm not certain how much actually has to do with the Parsha - it may be mislabeled) Rav Shachater quoting the Rav, explains as follows:
There is a common question that why does the Gemara support being machmir for Beit Shammai, yet by Kriat Shma, there is a strong condemnation of he who does like Beit Shammai and davka sits while reciting Shma at night (or stands in the morning). The Rav felt that the question never gets off the Ground since in this case, Beit Hillel's opinion that Kol Adam Korei Kedarko based on Belechtecha Baderech precludes going out of one's way to perform Kriat Shma sitting/standing. Beit Hillel hold that you must say Kriat Shma as you are, and therefore, being machmir for Beit Shammai ends up with you not holding like Beit Hillel.
Kriat Shma - must done without disturbing one's physical routine
Shmoneh Esrei - must stand erect, feet together, facing Yerushalayim

Netilat Yadayim

Why do we wash after we go to the bathroom, but clearly we're not doing it for sanitary reasons (not allowed to use soap)?
We wash every time something gashmi enter or exits our body. Both before we put something in (bread and maybe wet fruit) and after we relieve ourselves we wash our hands. Only for snacks, we aren't required to wash as it would be too tedious. The reason why washing hands specifically is connected with our body's interaction with the gashmi world still needs understanding. What do hands/water symbolize?

Covering Eyes for Kriat Shma

Why do we cover our eyes when we read the first pasuk of Kriat Shma? We say "Shma Yisrael" - in order to focus on the listening (maybe Torah She'ba'al Peh) we must block out our eyes (Torah She'bichtav). Especially in light of the surrounding pesukim in Ve'etchanon, which speak of Reiah and Shmiah constantly, since this pasuk speaks only of Shmiah, it makes sense to make an effort to exclude the Reiah. A N"M between this and the somewhat difficult approach of saying we cover our eyes for Kavana (difficult since we need Kavana in Shmoneh Esrei Avot as well) is whether to cover the eyes for Baruch Shem also.

HKB"H as Makom

HKB"H is sometimes referred to as Makom. Perhaps the pasuk (Shemot 33:21) where Moshe asks to see Him and Hashem responds "Hinei Makom Iti" can help clarify this terminology. Hashem does not say "Hinei Makom Etzli" or "Al Yadi" but rather "Hinei Makom Iti" - that within Me is Makom.

Kriat Shma vs. Shmoneh Esrei

I am working on a larger topic dealing with the differences between Kriat Shma and Shmoneh Esrei, inspired by an article in Rav Soloveitchik's Shiurim Lezecher Avi Mori. Please feel free to add to this list:

The Metzaref (from the Rav)
Kriat Shma - Barchu (hence no barchu by Mussaf/Mincha)
Shmoneh Esrei - Kaddish

Hefsek
Kriat Shma - Gemmarah discusses Bein Haperakim, etc.
Shmoneh Esrei - Afilu Nachash Karuch Al Ikvo

Language
Kriat Shma - only in Lashon Hakodesh
Shmoneh Esrei - Bechol Lashon

Chiyuv
Kriat Shma - Beshochbecha Uvekumecha
Shmoneh Esrei - 3-5 times a day

Kattan for 10th

How come if you are one man short for a minyan, you can only use a Kattan for the 10th and not a Shoteh or an Eved?
A Kattan has certain kedushah already as the future of Klal Yisrael.
