what does the bible say?
The word palingenesis comes from Greek roots meaning “again” and “birth.” In the nineteenth century, it was used in evolutionary biology to describe the false idea that human embryos pass through earlier animal stages before birth, beginning as a fish, then an amphibian, a reptile, a bird, and finally a mammal. Ernst Haeckel’s drawings popularized this theory in schools, but later research exposed them as inaccurate, and the concept was rejected.
Outside of science, palingenesis has also been used in philosophy and religion to describe rebirth or renewal. In Eastern religions like Hinduism, it refers to reincarnation—the repeated cycle of death and rebirth. Politically or culturally, it has been used to describe a nation or movement “rising from the ashes” after collapse.
In the New Testament, the Greek word palingenesia appears twice: in Matthew 19:28, where Jesus speaks of the coming renewal of the world, and in Titus 3:5, where Paul uses it to describe the cleansing process of salvation. Elsewhere, related terms such as “born again” (John 3:3) and “born anew” (1 Peter 1:3, 23) describe the same divine work. In each case, Scripture presents new birth as a once-for-all act of God’s grace which brings a real and lasting transformation through Christ.
