Recently, I completed reading one of the most important books I have read in some time: George Marsden?s The Twilight of the American Enlightenment: The 1950s and the Crisis of Liberal Belief. Marsden is arguably one of the most significant evangelical Christian historians writing today. I have read all of his books, which have profoundly shaped my understanding of both American history and of American evangelicalism. This most recent of Marsden?s books helps us immensely in understanding the crisis currently unfolding in American civilization. I would like to summarize the major arguments of Marsden?s book and then offer some implications about where we as the church of Jesus Christ go from here.

In 1947 C. S. Lewis published The Abolition of Man, in which he charted the ?negation of human dignity in the name of progress, or compassion, or humanity, or science.? He lived long enough to see the accuracy of his assessment: ?For the power of Man to make himself what he pleases means, as we have seen, the power of some men to make other men what they please.? Planned Parenthood, in its harvesting of fetal body parts and in its view of the human being, manifests ?the negation of human dignity? and an effort to ?make men what they please.?

Quite amazingly, a ?vaccine doubter? movement is growing in America. Those who adhere to this elixir believe that the risks of vaccination are much greater than the risk of the diseases vaccines are supposed to prevent. This is especially stunning because, in the words of columnist Daniel Henninger, ?Life without serious disease for the majority is now taken for granted as the natural order. The young don?t sign up for health insurance because they don?t need it. Forgotten over time is the extraordinary human effort and intelligence that produced the good life today. . .? As a result of the anti-vaccination movement, US measles cases have jumped 300% from 2013 to 2014. Others have made vaccinations an ethical issue out of concern over the source of some vaccination serums. According to a Pew Foundation poll, today about 9% of Americans consider vaccinations unsafe!

In the nation states that comprise today?s Middle East, only one nation offers protection and civil rights to Christians?Israel. Within Israel, Christians (many of them Arab in ethnicity), Jews and Muslims coexist under the protection of the state. There is no other nation in today?s Middle East offering such protection. In fact, today?s Middle East is witnessing the obliteration of Christianity in most of the region. This is astonishing because Christianity predates Islam by 600 years. It is in the Middle East where Christianity itself was born. Jesus Christ lived His entire earthly life in the Middle East and His apostles took the Christian faith throughout the Middle East.

The deep-seated commitment to the pursuit of personal autonomy, the vital center of the Postmodern, Postchristian American culture, has produced several effects. The Millennials, who passionately have bought into this commitment, have no loyalty to institutions. For that reason the local church, even if they are Christians, is not that important to them. Technology has enhanced this pursuit of autonomy, enabling millennials to create and fashion their own digital reality. . . But, embracing the pursuit of autonomy as the chief goal of life has also produced dysfunction, disorientation and confusion. Many millennials are experiencing an identity crisis. In this Perspective, I want to focus on two major illustrations of the growing evidence of this identity crisis in early 21st-century American culture.

In mid-July 2015, Iran and six world powers plus the European Union (EU) announced an historic agreement that seemingly postpones Iran?s capacity to build nuclear weapons. Arguably, Iran has suffered economically and financially under a series of sanctions the world community has imposed over the last several years. This agreement will lift those sanctions in exchange for a postponement of Iran?s nuclear weapons development. But it is also arguable that the agreement legitimizes Iran as a threshold nuclear state.

As she feasted on a luncheon salad and sipped wine, Dr. Deborah Nucatola, Planned Parenthood?s senior director of medical services, nonchalantly discussed how she methodically conducted late-term abortions to collect and preserve key fetal tissue and body parts. She declared that there is a great demand for fetal livers, but ?A lot of people want intact hearts these days.? To preserve intact fetal organs, Dr. Nucatola stated that ?We?ve been very good at getting heart, lung, liver, because we know that, so I?m gonna crush that part. I?m gonna basically crush below, I?m gonna crush above, and I?m gonna see if I can get it all intact?. . .This chilling video was released by the Center for Medical Research, an activist group seeking to expose Planned Parenthood for its abortion work and its nefarious disregard for prenatal human life.

The defense of Christianity and its claims has always been important throughout the history of the church. However, today the need to defend genuine, biblical Christianity is more important than ever. The Millennials of Postmodern, Postchristian America value personal autonomy more than anything else and give evidence of a significant lack of trust in all institutions, including the church. Millennials are therefore spiritually vulnerable.

The existential threat to Israel is real and has been since Israel was founded as a modern nation-state in 1948. The four major wars Israel has fought plus the numerous terrorist threats have defined Israel since its founding. But there is a new aggression being leveled at Israel?an economic aggression in the form of the boycott, divestment and sanctions (BDS) campaign. Members of the European Union (EU) are working to develop economic sanctions designed to force Israel to accept political concessions such as ending the blockade against Hamas in Gaza. Further, major EU banks and financial firms have blacklisted various Israeli banks because they operate in the West Bank.

At the end of June, the Supreme Court of the United States predictably ruled in favor of same-sex marriage in a 5-4 vote, with the majority opinion written by Justice Anthony M. Kennedy. The ruling overturned all state prohibitions or regulations against same-sex marriage, in effect making same-sex marriage equal in the eyes of the law as monogamous, heterosexual marriage. This decision comes exactly two years after Kennedy?s majority opinion in US v. Windsor, which struck down a federal law denying benefits to married same-sex couples, and exactly 12 years after his opinion in Lawrence v. Texas, which struck down sodomy laws in the states. Justice Kennedy based this most recent decision on the 14th Amendment and its ?equal protection? and ?due process? clauses.
