Matthew 12:31-32 Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men. And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come.
Now you posted this verse in the topic Trinity: are you joking. I really don't understand why, when the verses you posted were talking about the HOly Spirit, but you were asked about the Son and yet, say they are different persons. Maybe you misunderstood the question or something else...
But anyway to the point. Now we have Christ saying if you speak against Him it will be forgiven, but if you speak against the Spirit it will not.
So if I blasphemy the Son who is God, have I blasphemied the Spirit which is God?
Do I have to specify which person I'm blasphemying?
If I blasphemy God, then I have blasphemied all three, if there is only one God made of three persons, right?
To blasphemy the Son is to blasphemy God, yet the Spirit is that same God in trinity. So how is it possible to blasphemy the Son and be forgiven, when you have blasphemied all three by blasphemying God?
If you don't understand the questions, I can try and simplify them for you...
