First of all I think a lot of terrible misconceptions are being thrown around.
First of God is NOT a creation, therefore He isn’t capable of anything. He Is.
To ask the question is God capable of this…Misses the whole point. God cannot be measured, because God is God. Therefore asking questions “how strong is God, how old is God, is God capable of doing xyz?” seeks to bring God down to our natural level. God is not natural and neither is God supernatural (for angels are supernatural and God created those too) God Is.
Now as the Church states over again:
III. GOD, “HE WHO IS”, IS TRUTH AND LOVE
214 God, “HE WHO IS”, revealed himself to Israel as the one “abounding in steadfast love and faithfulness”. These two terms express summarily the riches of the divine name. In all his works God displays, not only his kindness, goodness, grace and steadfast love, but also his trustworthiness, constancy, faithfulness and truth. “I give thanks to your name for your steadfast love and your faithfulness.” He is the Truth, for “God is light and in him there is no darkness”; “God is love”, as the apostle John teaches.
God is Truth
215 “The sum of your word is truth; and every one of your righteous ordinances endures forever. and now, O LORD God, you are God, and your words are true”; this is why God’s promises always come true. God is Truth itself, whose words cannot deceive. This is why one can abandon oneself in full trust to the truth and faithfulness of his word in all things. the beginning of sin and of man’s fall was due to a lie of the tempter who induced doubt of God’s word, kindness and faithfulness.
216 God’s truth is his wisdom, which commands the whole created order and governs the world. God, who alone made heaven and earth, can alone impart true knowledge of every created thing in relation to himself.
217 God is also truthful when he reveals himself - the teaching that comes from God is “true instruction”.When he sends his Son into the world it will be "to bear witness to the truth “We know that the Son of God has come and has given us understanding, to know him who is true.”
God is Love
Over and over we read and hear God is Love, and that’s precisely what God Is. Love and Truth is what God Is.
Also God does not hate sin. Hate is evil and God is not evil.
Here is something I copied from another forum from Father Sotelo
The problem with a human reaction like “hatred” is that it describes what we humans experience when others have betrayed us, hurt us, harmed us, or threatened us in some way.
God is above this world, beyond time and space, infinite in His good attributes and changeless in His perfections. This is what makes Him God. So, He does not have mood swings and emotional hot flashes like we do. He is not fickle, confused, or undecided about what to do next. Thus, even when the Bible describes God as “hating” something, we have to be careful and realize we are using human language and human emotions to describe a Supreme Being who is way above being like us; He is way above acting like us.
Once He creates something, and it has come forth from His hand, He is always going to accept that creature as having a part of Him, being a reflection of Him. Our immortal soul was created directly by Him when He gave us life at the moment of conception. He directs our soul towards love and wisdom, and insofar as we progress on the good path we render unto Him glory, since our merits and goodness are His gifts to begin with.
When we sin, He is displeased that we have harmed ourselves, and detracted from the glory we should render unto Him. His love is His providing care (Providence); it is His holy will that we do what is according to His plan, fall back into line, get back onto the good path, and fulfill the ends for which He sent us into this world.
God cannot “hate” us; He can be displeased and offended by our decisions, but the immortal soul He sees in us came from Him and is a spark of His Being. To hate it, He would have to hate Himself, which He cannot do. To hate us; He would have to decide that He will stop providing for us to move towards the goals He set for us. But He can never turn away from His Providence because it directs all creation wisely. To hate us, God would have to become stupid and unwise; for a moment, He would have to be neglectful of creation, instead of Provident.
So, it is God’s nature, His Being and part of His perfection, to always love, and to always provide for, His creatures. If, at the moment of death, we have died unrepentant in mortal sin, and have decided to reject Him for good, He will send us to hell.
But that is not because He is a mean-spirited, hateful Being, but rather because He is just and fair and respects our free will. Dying in mortal sin is saying, “I don’t want to be with God in heaven.” God honors that decision and separates us from the elect and sends us to a different place. It would be unjust for God to send unrepentant sinners to heaven after they have emphatically decided they don’t want to be with God and the saints.
