Henry Edward Manning (1808 –1892) was an English Roman Catholic Archbishop of Westminster and a cardinal. Manning was very influential in setting the direction of the modern Catholic Church. His warm relations with Pope Pius IX and his ultramontane views gained him the trust of the Vatican, though "it was ordained that he should pass the evening of his days in England, and that he should outlive his intimacy at the Vatican and his influence on the general policy of the Church of Rome." Manning was among the strongest supporters of the doctrine of papal infallibility, unlike Cardinal Newman, who believed the doctrine but thought it might not be prudent to define it formally at the time. Manning used this goodwill to promote a modern Roman Catholic view of social justice. These views are reflected in the papal encyclical Rerum novarum issued by Leo XIII. It is the beginning of modern Roman Catholic social justice teaching.
