I think scripture indicates that they have a relationship. For example they said "Let us make man in our image". And Adam and Eve were created...two were created.
In a perfect marriage, two are one. They have one desire, one goal, one aim, they live together in perfect harmony...they are a unit but they have different talents and different roles.
Same with the God the father and Christ. They are one in unity and purpose, yet distinct. The love they have and share is something we can only experience in the smallest of ways, but even that smallness is great.
That's how I picture it at least and it will be a great blessing to see the reality.
I went with in laws to a Catholic Church service on Christmas Eve and the priest was referring to Jesus as God. This made me uncomfortable. Jesus is not God the father, at least that is what I was taught. Jesus was a God’s son made flesh.
