I'm personally am unclear of what you are asking for? what purpose or use do you want out this, if you want a practical lecture there are ample across many topics, with no religion involved. A sermon by its nature is one of a religious or moral nature. and is often based around not literal matters. what do you see what your asking for looking like? All I can think of maybe something from the Unitarians (https://www.uua.org/worship/words/sermon https://www.uua.org/worship/words/sermon)
