>>713178447that teaching is referring to people trying to gain wordly validation by being seen praying in public, messing up their hair to look like they're fasting etc. - the prohibition is against public prayer for the explicit prupose of being seen praying/thought of as a spiritual person, etc. the bible clearly teaches the existence of an ecclesia/church/assembly where Christians worship collectively (see Matthew ch18, acts ch20 as two examples, there are plenty more but I am not going to exhaust the point here)
