One of the skills of the Sotāpanna is being a part of the right speaking 'Noble Sangha', which includes the Lay Community.
As a separate category, those who have attained any of the four stages of enlightenment, whether or not they are members of the monastic community, they are referred to as the āryasaṅgha "noble Sangha"
Right speech in my view, varies from dogma and is related to how it is heard. So for example in Sufism, some would be students are warned against spiritual practice as they need life experience.
Would a Buddhist dogmatist insist that meditation or mindfulness is always helpful, when in fact mantra, sadhana, study or just devotional activities might be more appropriate in certain circumstances?
How does this relate to skilful means?
