Cardinal John Henry Newman was a prominent 19th-century theologian and writer, known for his influential role in the Oxford Movement, which sought to revive the Catholic heritage within the Church of England. Born on February 21, 1801, in London, he initially served as an Anglican priest before converting to Roman Catholicism in 1845, which significantly impacted his theological views and writings. Newman became a cardinal in 1879 and is best known for his works such as "Apologia Pro Vita Sua" and "The Idea of a University." His thoughts on faith, reason, and education continue to resonate, leading to his canonization as a saint in 2019.
