In Islam, there is no priesthood and each person stands before God, like in the daily prayers, without an intermediary. That's in contrast to Christianity, where during the Eucharist, a priest has to officiate and the priest functions as a link - at least in Catholic Christianity - between the laity and God.
Seyyed Hossein NasrThere are millions and millions of Sufis who have existed in Islamic history and have the deepest impact on every aspect of Islamic culture and civilization to philosophy to art to science to social structure to economics who have not met the destiny of al-Hallaj.
Seyyed Hossein NasrTariqah [The Spiritual Path] without the Sharia [Islamic Law] is like having a pistachio tree without the shell. Or a walnut, a walnut cannot grow on a tree without having a shell, and the food that you eat is inside the shell.
Seyyed Hossein NasrIf God did not love us, we could not love him. And Sufis are those who have realized this love.
Seyyed Hossein NasrIf you have a billion Muslims, 900 million of them were not brought into Islam by any kind of invasion, but most of them through the Sufis, because human beings are such that they are affected by people of spiritual character. Certainly when they display nobility and hospitality and gentility and love and are not selfish or aggressive, and they are honest.
