[Here I want to address Senator Portman directly.]
To state it bluntly, Senator Portman, Christianity, the Word of God, and the proper view of homosexuality has nothing to do with you or your changing perspective. It has everything to do with the unchanging Word of God. Your attempt to cloak your opinion by distorting the Word of God is not only offensive but blasphemous. I encourage you to open your Bible and read what it says about false teachers and those who add to or take away from the Word of God.
I understand that your son is a homosexual. As a Christian you are called to love him but you cannot condone his sin and encourage others to do the same. Principles are higher than our individual circumstances. Principles do not change because the circumstances in our lives change.
He who loves father or mother more than Me is not worthy of Me. And he who loves son or daughter more than Me is not worthy of Me. And he who does not take his cross and follow after Me is not worthy of Me. He who finds his life will lose it, and he who loses his life for My sake will find it. (Matthew 10:37-39)
Condoning the sin of homosexuality will not help your son to lead a “happy, meaningful” life. He cannot lead such a life in direct opposition to the Word of the Lord. You have taken the easy path and it will only lead to sin and death, error, and worse.
My prayers are with you and your family but Christians must not let your attempt to pervert the Word of God to fit your own personal life go unchallenged.
