Do I use a plural?

Question

This is what I am trying to firgure out. When I write this sentence, do I write it as a plural?

Estimado Amigos y Amigas en Cristo

Do I use Estimados or Estimado?

Thank You

Answer 1

"Estimados Amigos", there's no need for "amigas" since "amigos" can be used to mean both male and female friends.

On top of that its "Amigos Estimados", not "Estimados Amigos" the friends are the dear ones, not the dear are friends.
