Catolicism belief is without further discussions in Trinity - Holy Father, Holy Son and Holy Spirit(which had earlier representation of anthropomorphic Jewish God).

Since no one really has read a Bible, I can remind the source:

>>Then God said, “Let us make mankind in our image, in our likeness, so that they may rule over the fish in the sea and the birds in the sky, over the livestock and all the wild animals, and over all the creatures that move along the ground.”

>>"So God created mankind in his own image, in the image of God he created them; male and female he created them."

According to Bible - God created humans in his image - this is very problematic passage for Christianity, if there is an alien life out there, because apparently they would not be createad by a God.

Any deviations from anthropomorphic nature of a God in Christianity does look like a herecy. Because any other deviations from Christian religious dogmas basically brings to the result, where Aztec god that requires sacrifices and Sol Invictus, not to mention Allah and Yahweh are the same immanent transcendences of a God.
