In contrast with some extreme currents, there is Imam Khomeini's and Ayatollah Khamenei’s logical viewpoints based on their religious knowledge: firm belief in protecting the structure of the Islamic Republic, or better said, the religious people-oriented [democratic] system. 

In the viewpoint of Imam Khomeini and the Leader of the Islamic Revolution—Ayatollah Khamenei— religious democracy is not just another political theory among man-made political systems.   Rather, it has strong religious foundations based in Fiqh [jurisprudence], and that is why Ayatollah Khamenei expressly announced that: 

" I have, genuinely, cherished religious democracy. We truly believe in religious democracy. We consider everyone who has been elected by the people as the chief and as the official in charge. We consider helping them as essential, and we consider it our responsibility.” ( Jan 9, 2018) 

With this perspective, mistaken definitions of Wilayat al-Faqih [the rule of the jurisprudent] has no place in the democratic system of Iran." 

 The kind of Vilayat-e Faqih which was introduced, defined and implemented by our magnanimous Imam is a kind of dynamic, flourishing and progressive management. 

 Imam Khomeini was a perfect manifestation of this Vilayat-e Faqih and over time his outstanding characteristics became clearer to whoever knew him well. 

Imam Khomeini promoted the idea of absolute Vilayat-e Faqih. 

 Some people resorted to fallacious reasoning and tried to distort the issue in one way or another. They tried to impose a wrong meaning and interpretation on the concept. 

 They said that absolute Vilayat-e Faqih means that in the Islamic Republic the Leader is above all the laws. 

 They said that absolute Vilayat-e Faqih would give leaders of the Islamic Republic unlimited power to do whatever they wanted.

 This is not the case.

 Our magnanimous Imam was more committed than everybody else to observing the laws, the principles and the details of divine commands and this is the duty of the Leader.
