The Korban mussaf on Shabbos is different from all the other mussafim. Every one of the Mussafim has a Sa’ir L’Chatas except for Shabbos. Why is Shabbos different in that is has no Chattos?
The Pachad Yitzchok has a beautiful thought. Rav Hutner writes, the first time we have Ein Mukdim U’muchar B’Tora is in Parshas B’reishis. B’reishis starts with the first day, second day, third day... then after the sixth day, Vayichulu Hashamayim and the description of Shabbos. This is out of order because the original Cheit of Adom took place on the sixth day. Shabbos is spoken about before the Cheit even though the Cheit took place earlier. Why is that so?
Rav Hutner writes that Shabbos is a day of Kedusha on which we have the ability to connect to the Ribbono Shel Olam in a way that is L’maylo Min Hacheit. Shabbos has a level of D’veikus with Hashem that makes it K’ilu there never was a Cheit. If the Cheit of Adom was written first and then Shabbos, it would be a Shabbos that was L’achar Hacheit. Shabbos is really L’mayla Min Hacheit. If someone uses Shabbos properly, he can connect to Hakadosh Baruch Hu.
Shabbos is special in that Hashem is close to those people who are M’aneig on Shabbos. The Zohar compares it B’derech Mashul to a father who gets down on his hands and knees and plays with his child. Since Shabbos is L’mayla Min Hacheit, it has no Korban Chattos. That is Pshat in what we say in Mussaf, Tikanta Shabbos Ratzisa Korbanoseha, that Hashem established Shabbos and found favor in its offerings. Normally, for mussaf, a Korban Chattos is offered first and only then is the Olah brought. On Shabbos, there is no Korban Chattos brought, and we go straight to the Korban Olah.
Rebbi mentioned that he hopes that we who are in the working world now are using Shabbos properly in our Avodas Hashem, and we should be Mekareiv our children in the Ahavah of Yo m Hashabbos, to see the Kedushah of Yo m Hashabbos. In addition, Rav Hutner adds, the Posuk says Vayar Elokim Es Kol Asher Asah V’hinei To v M’od. Hakadosh Baruch Hu looked at everything and said it is good. Once He said it was good, the B’riya was able to continue. That idea that an Ayin To v a gives a Kiyum to the B’riya is something we have to appreciate.
