Manipulation is not exactly witchcraft, so you need to be careful in how you define witchcraft. In the Bible witchcraft is sorcery. And sorcery is not practiced in Christian churches (even in the liberal ones).
כָּשַׁף kâshaph, kaw-shaf'; a primitive root; properly, to whisper a spell, i.e. to inchant or practise magic:—sorcerer, (use) witch(-craft).
True, witchcraft is not openly practiced in any Christian church, but it's practiced regularly by MANY who use chemical contraceptives.
The contraceptive mentality is evil
of the same root as abortion. It is, IMO, the great deception because MOST Christians of any stripe are contracepting. That is one reason the world, the flesh and the devil hates the Catholic Church so much, and in doing so tries to discredit her moral authority, to achieve its diabolical ends. (follow the money)
Malachi 2:14 – marriage is not a contract (which is a mere exchange of property or services). It is a covenant, which means a supernatural exchange of persons. Just as God is three in one, so are a husband and wife, who become one flesh and bring forth new life, three in one. Marital love is a reflection of the Blessed Trinity.
Malachi 2:15 – What does God desire? Godly offspring. What is contraception? A deliberate act against God’s will. With contraception, a couple declares, “God may want an eternal being created with our union, but we say no.” Contraception is a grave act of selfishness.
Ephesians 5:25 – Paul instructs husbands to love their wives as Christ loved the Church, by giving his entire body to her and holding nothing back. With contraception, husbands tell their wives, "I love you except your fertility, and you can have me except for my fertility." This love is a lie because it is self-centered, and not self-giving and life-giving.
Revelation 9:21
Revelation 21:8
Revelation 22:15
Galatians 5:20
These verses mention the word “sorcery.” The Greek word is “pharmakeia” which includes abortifacient potions such as birth control pills. These pharmakeia are mortally sinful. Moreover, chemical contraception does not necessarily prevent conception, but may actually kill the child in the womb after conception has occurred (by preventing the baby from attaching to the uterine wall).
Contraception is a lie that has deceived millions, but the Church is holding her arms open wide to welcome back her children who have strayed from the truth
Little girls do not grow up dreaming of hopping from bed to bed and contraception. They dream of a man who will sweep them off their feet and love them forever, and of having his many children. A cynicism born of the sexual revolution has brought emptiness to the hearts, wombs and lives of far too many modern women. This emptiness and pain can be avoided or redeemed and healed by the love of Christ and adherence to His teachings. The Catholic Church believes in such dreams because God wrote them on the human heart. And there are men who long for such a woman to love and cherish.
Real lovers want to give without reserve in God's own superabundance creating more hearts and lives to love.
Contraception is like kissing through a screen door and real love cannot tolerate obstacles. Contraception breeds selfishness and separation that drives a wedge between husband and wife that kills love. Real lovers want their love to explode into the posterity of future generations for all eternity.
This is the kind of passion and fulfillment God wants for His children. Contraception limits what should be boundless.
It spits in the face of this glorious passion and love's true abandon; and that is why it is a sin. It seeks to "tame" love, thus killing it. The Catholic Church is the last bastion on earth of true romance.(true romance is found outside the walls of the Catholic Church)
The modern world has suffocated love and made sex a thing of deadness.
