Fr. Joannes Antonius Gerardus Lohuis O.Carm. was born in Oud-Ootmarsum, the Netherlands on August 25, 1924. He entered the minor seminary in the Netherlands and then joined the Carmelite Order in 1947. On October 14, 1948, his had first temporary vows. When he was studying as a Carmelite student, the Prior Provincial of the Netherlands offered the students who were interested in a mission to Java, to go to Java and complete his studies there. The purpose of this program was to prepare themselves in doing the mission there. Some students were interested and one of whom was Bro. Joannes Antonius Gerardus Lohuis O.Carm. 

Along with some other students, he sailed from the Netherlands to Java. They all arrived in Java on 3 May 1951. Bro. Lohuis and the other students continued their study at the Carmelite convent of Regina Apostolorum Batu. On December 19, 1954, Bro. Joannes Antonius Gerardus Lohuis O.Carm. was ordained as a Carmelite priest by Mgr. Antoine Everard Jean Avertanus Albers O.Carm. at the Cathedral of Our Lady of Mount Carmel, Malang.After his ordination, he returned back to the Carmelite convent Batu to complete his study. After completing his entire study in October 1955, he was assigned to be the co-pastor at the Parish of Lumajang. He completed his task in May 1956 when he got a new job as the co-pastor at the parish of Celaket Malang. His task is to serve the Catholics in some stations in South Malang, which were parts of the Parish of Celaket Malang.

When the diocese of Malang founded the Parish of Purworejo, Fr. Lohuis got a new task to become the parish priest of Purworejo parish. He worked as the parish priest of that parish from 1960 until September 1970. In those years he was really busy serving the people in South Malang not only spiritually but also materially. Between the years of 1965 and 1970, he made a large contribution in saving the souls of the simple people of South Malang who were accused of being members of the Communist Party of Indonesia. At that time many people converted into Catholicism because of the good example of Fr. Lohuis and of his struggle to save them. In 1970, when famine threatened the people of South Malang, he acted as their savior by distributing rice-skin porridge and milk (granted by the Catholics in Germany and the Netherlands).

In 1970, the Parish of Purworejo was divided into two parishes, the Parish of Purworejo and the parish of Lodalem Arjowilangun. Fr. Lohuis, himself, chose the abandoned land in Lodalem. He liked the area because if the name of the area is translated into Dutch, the meaning was similar to his family name (in Javanese ‘Lodalem’ comes from the word ‘Lo’ which means ‘Lo wood’ and the word ‘dalem’ which means ‘home’. This means ‘Lodalem’ means ‘Lo wooden house’. In Dutch language the name of ‘Lohuis’ if is separated into ‘Lo’ (no meaning in Dutch) and ‘huis’ (meaning ‘home’), also means ‘Lo wooden house’.

Fr. Joannes Antonius Gerardus Lohuis O.Carm. who were a hard worker, participated personally in the construction of the rectory. He did not stay silent or just give orders. He also help the workers to lift building materials. On August 8, 1973, when I was by himself lifting concrete aqueducts bus, he got a heart attack. When tha sacristan at the time, Mr Yanto, went back to the priory after returning to his home for a moment, he found Rm. Lohuis lying on the ground. He was rushed to the Catholic hospital in Malang but unfortunately it was too late. He died on that day. He was 49 years old, had been a member of the Carmel for 25 years and became a priest for 19 years. In accordance with his request, he was buried at the park behind the Catholic Church of Lodalem on August 9, 1973.

Until now many good people from the parish and surrounding parishes, either Catholic and non-Catholic, visit his tomb. He is regarded as a saint by them. It is not surprising that when they encounter a problem or face an exam, they come on pilgrimage to the tomb of Fr. Joannes Antonius Gerardus Lohuis O.Carm. and ask him to pray for them to God. Many people admit that they obtain the grace of God through this pilgrimage.
