Christ came to deliver us from all evil, especially sin and death, but the underlying cause of evil is a person, Satan, the Evil One and his followers. He was the brightest angel who opposed God in the beginning and continues to this day.
He is the underlying influence in our society which is permeated with a false sense of freedom which masquerades under the aspect of human rights. And so women claim to have a right to abortion and gays claim a right to marriage. What is a right? A right is something owed to you because of the nature God has given you. Therefore, a woman has a right to beget life but not to destroy it. Gays and lesbians have no right to marriage because only love between man and woman can beget life. This is in the nature of things or Natural Law. St. Paul has well said that our "Struggle is not with flesh and blood but with the principalities, with the powers, with the world rulers of this present darkness, with the evil spirits in the heavens." (Eph 6:12)
For the Baptized Christian it is Jesus Christ who defeats in us the influence of these powers of wickedness. Through right reason and the Church we receive the true interpretation of the world. The power of sin and death is broken because in Christ there is the forgiveness of sins and the promise of future glory. But, this cosmic struggle will not end till the end of time when we can say,
"Now have salvation and power come,
and the kingdom of our God
and the authority of his Anointed.
For the accuser of our brothers is cast out...."
For the Kingdom....
