How should a lay person respond if they see a monk teaching something contrary to Dhamma? Let's say if a lay person sees fault of a monk (something against the monastic code, or against the Dhamma). Should the lay person just stay silent (thinking it would create bad karma), or should they do something about it (showing the monk what he has done, or letting others know about it)? 

Are there any Sutta references on what the Buddha said about this?

I have seen a lot of monks doing things against the monastic code and the Dhamma, and it breaks me up to see that people who know about it are silent; and that, day by day, the Dhamma is fading away because of this. What has the Buddha instructed to a lay person, on situations like this?

Since Buddha Sasana is not only monks and nuns, but also lay man and lay woman as well, what are the lay person's responsibilities towards the Sasana? 

(Sutta references are appreciated if any)



Recently me and my Meditation teacher encountered a monk who stated in one of his statement saying that the Buddha has advised lay people not to comprehend the 4 truths but to get rid the 4 states of misery. For me and my teacher, it was shocking since all of Buddhism is based on the 4 truths. Therefore we created a video on the monk's statement and give a detailed explanation on how wrong the statement is and how it should be corrected and we uploaded it on youtube knowing that the messaged would spread to that monk. And within 3 days of time it did.

At first, they didn't accept it but at the end they did accept their statement as wrong. And we took the video down since our mission accomplished. Our intention was for us to show that monk's fault and for him to recognize it and correct it. But now someone people are saying that it's a sin to do that and that we should not intervene with monks' things. But we were to stay silent when Monk themselves are spreading wrong statements, will the sasana survive? Isn't it selfish to stay silent where as we cans how what is right or wrong despite one is a monk or a lay person?
The word sangha is used nowadays to refer to the bhikkhus. This may or may not be true. One does not have to be a bhikkhu to belong to the sangha. An Upāsaka (male) or Upāsikā (female) - lay followers – could also be part of Arya Sangha. Upāsaka and Upāsikā are part of Ariya Sangha, once in the Path. The Ariya Sangha is described as all those who have attained at least the stage of Stream Entrant. 

A bhikkhu is someone who has renounced the life of a layman to dedicate himself exclusively to practice, realization, study and teaching of the dhamma. But in the present day and age, there are a great number of bhikkus who have not come to the stage of Stream Entrant. Thus they are not part of Arya Sangha.

There were times when Hattha Āḷavaka Ugga gahapati (householder) preached dhamma to the Bhikkus at the time of Buddha, when no one else came forward to speak on Dhamma.. 

The Buddha does not advocate superficial unity for its own sake between bhikkhus or amongst bhikkhus and lay followers at the expense of the Dhamma. Buddha instead encourages that the Dhamma be clearly defended against non-Dhamma and that the distinction between the two be kept clear.

Buddha has described in no less than six suttas about what one should do at such an instant. In the Sangha Bedha Sutta (AN 10.1.4.7), Buddha’s instruction is to not advocate superficial unity for its own sake at the expense of the Dhamma, but instead encourages that the Dhamma be clearly defended against non-Dhamma and that the distinction between the two be kept clear. According to the Vinaya, a speaker of non-Dhamma is to be recognized as such if he “explains not-Dhamma as ‘Dhamma’ … Dhamma as ‘not-Dhamma’ … not-Vinaya as ‘Vinaya’ … Vinaya as ‘not-Vinaya’ …

Thus the ability to take a stand requires that one be well-informed about the Buddha’s teachings. A difference of opinion can be rightfully ended only if both sides are able to investigate the grounds and get to the root, and then resolve which side was right, based on the Dhamma and Vinaya.
