We go by the New Testament. The Nicene Creed was an apostate edict issued over two centuries after the apostles' death. And the Trinity is an apostate interpretation of the Godhead - of the Father, the Son, and Holy Ghost, three separate Beings who are one and united in purpose. Jesus wasn't praying to Himself. He was praying to His Father.
I'm prolife. So I'm against baby-killing. And I certainly believe we should improve the adoption and foster care systems. There's no need for sperm banks and artificial inseminations and surrogate mothers. If a couple is infertile, there are plenty of kids in need of adoption.
As for migrants ... I'm all for reuniting the families as quickly as possible. What we really need is to improve the economies and political stability of Latin America -- solve the problems that these people are fleeing from.
