I had problems with this!
1A1ADelivered heartburn relief for non-trans person's arteries? (7)[-------]: I haven't seen "delivered" as a homophone, only an anagrind; I couldn't get "non-trans person", even seeing your parsing.
7A7ADecoration bears green starter (3)[---]; what is an ECO7ADecoration bears green starter (3)[---]?
1D1DChristian sect's salt and pepper vessels (7)[-------]; in my part of the world we don't call salt and pepper pots "shakers", so that was a mystery for me.
However, a decent cryptic. Well done.
