Anticipating religious objections to cultivated meat
I think that many Christians and probably many other leaders and followers of other religions will object to cultivated meat on the grounds that it is "unnatural" or "not how God designed it."
This is not an unusual argument in the slightest, and it tends to creep in every time there is an advancement in technology. Even with the advent of modern medicine, I remember reading how many religious leaders were skeptical and wondered if life-saving technology would interfere with God's will. Critics said that to course-correct illness would violate God's possible will for the person to die or not suffer - which is just bad theology. From a Christian's perspective, God's will is for humans (and animals) to live happy and healthy in good health for all eternity, as demonstrated by the garden of Eden in Genesis 1:20–30. God called Eden "very good" in Genesis 1:31. In Eden, there was no death, disease, or any suffering. All of those "bad" things came after the disobedience of Adam and Eve (Genesis 3:1–6). Now all of humanity is forced to live in this world filled with death, disease, and suffering (Genesis 3:16–19). A big part of Jesus coming to earth the first time was healing the blind (John 9:1–7), curing the sick (Matthew 8:1–3), and generally relieving the world's problems (John 8:12). The Bible promises that Jesus will eventually restore the world to the paradise God intended from the beginning. There will be no more death (Isaiah 25:8), disease, or suffering (Isaiah 35:10).
Just like Christians previously found modern medicine to be theologically questionable, they probably will find cultivated meat to be theologically questionable as well - since God did not design meat that way. However, advocating against slaughter-free meat and advocating that traditional slaughter continues is also terrible theology. Meat was not allowed (Genesis 9:3) until after God called humans "evil" in Genesis 8:21. Meat was not part of the "very good" vegan world God created in Eden (Genesis 1:29–31). After Jesus returns, the world will return to a vegan paradise, as seen in Isaiah 11:6–9. It is precisely the unnaturalness of cultivated meat that Christians should encourage the product. Humanity has been largely unable to live by the ideal of veganism that God wants (Genesis 1:29–30). Instead, cultivated meat offers an option where humanity can have the "evil" without animal torture, environmental destruction, and the detrimental cost to human health. Cultivated meat, like modern medicine, should be welcomed by Christians, as it reflects Revelation 21:4. The verse states, "He will wipe all tears from their eyes, and there will be no more death, suffering, crying, or pain. These things of the past are gone forever.” We as Christians also need to ask, "What Would Jesus Do?” Would Jesus, the “Prince of Peace” (Isaiah 9:7), want us to continue slaughtering animals when we had the ability and the power not to?
Some denominations, like the Seventh-day Adventists (SDA) and the United Church of God (UCG), still follow the kosher dietary restrictions of the Old Testament. Most denominations do not. I theologically believe they should be followed (my next book is about this, actually). Still, I foresee SDA and UCG type denominations having an issue over whether cultivated meat could be deemed kosher. I imagine that they would probably stick to only the meat acquired from kosher animals (Leviticus 11:2–3; 11:9). I would imagine that as long as the cultivated meat did not contain blood or come from a strangled animal (Acts 15:29), it would be kosher.
