Salaam brother Ron,
I couldn't agree with you more.
But in practical terms it is not so simple. As we evolve as society we face issues that there were not even conceived in the 8th or the 9th century, when the imams of the Sunnis lived.
Thus, we have salaf, the ibn-taymiyah/salafi/wahhabi, who are nothing but like the Mormons and/or Amish. They are all living in the past and couldn't care for reform.
Such as, birth control pills which was inconciebale at the time the Sunnis imams lived. Or the abortion, if it threatens the life of mother. Are we allowed abortion. At what stage we are allowed abortion and so forth. As the Ummah evolves, so does the jurisprudence has to evolve with the Ummah. Thus, requiring constant reform.
And, this reform has to come from the ulemas who are well versed in Islam. Not any Tom, Dick and Harry who call themselves ulemas.
