John Chapman (priest)
John Chapman OSB (25 April 1865 – 7 November 1933), received into the Roman Catholic Church at the age of 25, was a Roman Catholic priest, the 4th Abbot of Downside Abbey of the English Benedictine Congregation from 1929 until his death, an internationally respected New Testament and patristics scholar, a defender of the priority of the Gospel according to Matthew and a spiritual writer enjoying enduring appreciation.
Baptised with the name of Henry Chapman and the son of an Anglican canon of Ely Cathedral, he was educated privately and at Christ Church, Oxford (1883-6), where he received a first class degree in Classical Greats. He stayed for a subsequent year at Oxford reading theology, in which he took a third. It was an important year for him, however, because in this time he decided to take Orders in the Church of England.
Having trained at Cuddesdon, near Oxford, he was ordained as a deacon in the Church of England in 1889 and began a curacy in the parish of St Pancras', London. He found himself increasingly troubled during this time about the position of the Church of England and eventually left the parish soon after Trinity Sunday.
Conversion to Catholicism
He subsequently entered the Benedictine Maredsous Abbey in Belgium, when he was given the religious name of John. He professed simple vows on 25 March 1893, and made his solemn vows on Whitsuntide 1895.
After his priestly ordination in 1895, he went to Erdington Abbey, near Birmingham, where he stayed until 1912, serving the community as novice master and later as prior, but also frequently visiting the library of St Mary's College in nearby Oscott.
Having spent nine months at Maredsous, in February 1913, Chapman was made temporary superior of the Caldey island community (now based at Prinknash Abbey), when it was received into the Roman Catholic Church in 1913-14.
On the outbreak of World War I (1914–1918), Chapman first became a Professor of Theology at Downside Abbey, joining the many monks who had fled Maredsous to England.  In early 1915, when these monks moved to Ireland, he became army chaplain to the British forces. After initial training, his brigade arrived in France in July 1915. He lived in the trenches in autumn 1915, until a persistent knee injury led to him being sent to hospital in November 1915. After leaving hospital, he first was stationed at Boyton Camp, Wiltshire, for several months, and then returned to France. At the end of 1917, he was transferred to Switzerland, where multilingual chaplains were need for the POW camps. He remained here until the Armistice. 
4th Abbot of Downside
In 1919 Chapman transferred his monastic stability to Downside Abbey. He spent most of 1919-22 in Rome, though, working on a Commission on the revision of the Vulgate.  He returned to Downside in 1922, where in 1929 the community elected him Abbot. As 4th Abbot of Downside, during his short term of four years, cut short by his death on 7 November 1933, he carried on the work of Abbots Cuthbert Butler and Leander Ramsay. He completed the transformation of Downside into a modern abbey in the mainstream of the Benedictine tradition and in 1933 became the founder of Worth Priory, since 1957 Worth Abbey, when he bought the property, then called Paddockhurst, from Viscount Cowdray.
New Testament and patristics scholar
John Chapman was thought by competent critics to be the greatest patristics scholar of his time. Reputedly he had read all 378 volumes of Migne. However, he not only read both Greek and Latin with the greatest facility, but also read and wrote French, Italian and German with similar ease. Many of his contributions to biblical scholarship and patristics have proved of lasting value, especially his work on St Cyprian, St John the Presbyter (of Papias), and on the priority of the Gospel according to Matthew that, so Chapman argued in support of the early Church tradition, was the first Gospel account to have been written (see also Synoptic Problem).
Among the novices that Chapman clothed in the monastic habit was in 1932 John Bernard Orchard, who soon felt drawn to follow his Abbot into researching the priority of the Gospel according to Matthew in the light of the patristic evidence, and eventually, after also constructing a synopsis of the four Gospel accounts in Greek and English for the easier study of the compositional sequence Matthew-Luke-Mark-John that is supported by certain early Christian writers, produced what by hindsight may be considered a synthesis of his and his mentor's insights.
In his day Chapman was a much sought-after spiritual director and authority on prayer, the spiritual life and mystical theology. His writings remain of perennial value, especially his Spiritual Letters. An oft quoted advice of his was: "Pray as you can, not as you cannot!".
Man of many talents
According to his contemporaries, Chapman had a brilliant mind and was a fascinating conversationalist. He was also a talented pianist and a Christian humanist in the finest tradition.
