Katy Perry's Wikipedia page states Katy's mother, a preacher's wife, forbad Katy from eating "Lucky Charms" as a girl because Lucky was too much like Lucifer. One wonders if Katy had been allowed to eat the cereal if she would have ever kissed the girl? Katy eventually renounced the "Christian" faith of her youth, and became a New Age spiritualist.
No one who follows Jesus ought to be distressed by similar renunciations of "Christianity." In reality, what is revolted against is the abuse and perversion of Jesus' teachings and the life He brings. Jesus told us, "I came so you can have real and unending life, more and better life than you ever dreamed of having" (John 10:10, The Message).
Like Katy Perry, Robert Louis Stevenson (1850-1894)--author of books like Dr. Jekyll and Mr. Hyde and Treasure Island -- rebelled against his strict and unnatural upbringing. Stevenson was raised in a Scottish Calvinistic home where Law was emphasized to the neglect of God's love for sinners in Jesus Christ. As a young man, Robert Stevenson renounced his rigid upbringing which he described as "the deadliest gag and wet blanket that can be laid on a man." There was no such thing as New Age faith in Stevenson's day so he became an atheist.
However, as Robert Louis Stevenson turned forty years of age, he began to have "doubts about his doubt." He realized that though the world claimed to be able to give him life and wisdom, the world actually had no satisfying answers to the problems he faced.
At age forty-two Stevenson would write, "There is a God who is manifest for those who care to look for Him." Before Stevenson died two years later at age forty-four, he described his faith in Jesus Christ as "a cast iron faith." The last short story Stevenson wrote before he died was entitled Markheim, and it is a veritable "look in the mirror" for people like Katy Perry and others who renounce what they consider "Christianity," only to discover they've never really had faith in the first place.
If you were denied Lucky Charms in your youth by well-meaning but deceived parents, God's grace will eventually overcome your objections and bring you to an understanding that He alone gives real life through His Son, and this life is ultimately the only solution to the problems that plague us all.
