Peace Truthseeker1,
"First of all Catholics say that that there are Three persons in One and they are all separate as well."
Three in one. They are not seperate because they are one.
It cannot fully be explained, I don't believe.
But then, who can explain God?
Only an arrogant fool would dare claim he can explain God in His divine form!
...
"Secondly Catholics say that God the Father sent his only Son
Thirdly Catholics sometimes say that God came to earth as Man"
#2 is true.
#3 could be reworded.
God the Son came to earth as a man, Jesus.
"Now which one is it Did God come to earth as Man or did God send his son to Earth COZ if God came to earth as man then why would he call himself his own Son???"
God didn't jump off His throne and transcend to earth.
God can be everywhere at once.
And like I said, God the Son came to earth.
...
"It doesnt make any sense, why would God complicate things so much?? "
Please understand that if you choose to follow only what you fully understand, then you are NOT following God.
Would you honestly expect God to make sense to you?
Would you honestly expect God's plan to be uncomplicated?
Do not expect to understand God in His divine form, or His divine will.
Accept is like a small child excepts a gift from his loving father.
He lives to please his father for this really cool gift.
This is how you approach God and His gift of everlasting life,
We are like children to our Heavenly Father.
Have I helped you?
