The Chief Justice presides in the Senate during a president's impeachment trial. The rules of the Senate, however, generally do not grant much authority to the presiding officer. Thus, the Chief Justice's role in this regard is a limited one.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who has an unlimited role in this regard?
Ah, so.. unanswerable

In Epperson v. Arkansas, 393 U.S. 97 (1968), the Supreme Court considered an Arkansas law that made it a crime "to teach the theory or doctrine that mankind ascended or descended from a lower order of animals," or "to adopt or use in any such institution a textbook that teaches" this theory in any school or university that received public funds. The court's opinion, written by Justice Abe Fortas, ruled that the Arkansas law violated "the constitutional prohibition of state laws respecting an establishment of religion or prohibiting the free exercise thereof. The overriding fact is that Arkansas' law selects from the body of knowledge a particular segment which it proscribes for the sole reason that it is deemed to conflict with a particular religious doctrine; that is, with a particular interpretation of the Book of Genesis by a particular religious group." The court held that the Establishment Clause prohibits the state from advancing any religion, and that "[T]he state has no legitimate interest in protecting any or all religions from views distasteful to them."

Differences in feasts may also originate from doctrinal issuesthe Feast of the Assumption is such an example. Given that there is no agreement among all Christians on the circumstances of the death, Dormition or Assumption of Mary, the feast of assumption is celebrated among some denominations and not others. While the Catholic Church celebrates the Feast of the Assumption on August 15, some Eastern Catholics celebrate it as Dormition of the Theotokos, and may do so on August 28, if they follow the Julian calendar. The Eastern Orthodox also celebrate it as the Dormition of the Theotokos, one of their 12 Great Feasts. Protestants do not celebrate this, or any other Marian feasts.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When Mary finished attending all of the Feasts, what were the Feasts referred to as?
Ah, so..
unanswerable
