In early twentieth century Robstown, German and Moravian families migrated to the area to farm, but Czech-speaking Catholics could not find worship services in their native language. Father Joseph Klobouk, pastor of St. Boniface Parish in Corpus Christi, oversaw a community whose services were held for many years in a local home or in nearby communities until a former Methodist church building on East Avenue B and Second Street was purchased in 1924, giving Slavic Catholics their own place of worship. Named for St. John Nepomucene, a popular saint among Czech-speaking Catholics, it became a mission of St. Boniface Parish. Various priests served during the next decade until 1934, when newly ordained Father George Steven Scecina was appointed the first resident pastor of St. John’s and also pastor of St. Frances of Rome Mission Parish in nearby Agua Dulce, where he served from 1934 to 1961. Father Scecina remained pastor of St. John’s for the next 49 years. A new church was built and furnished on this site in 1937 for $17,504.39, and a rectory was added the following year. In 1945, Father Scecina had a convent and school built near the church, staffed by nuns from Indiana. By 1951, St. John’s taught classes from elementary school through high school, and in 1955 it graduated its first senior class of thirteen students. More than 320 students graduated from high school before it closed in 1970, while grades one through eight continued at the original site until 1986. Father Scecina died in 1988, and St. John’s continues to serve the Robstown area.
