In 1839 Giustino de Jacobis, an Italian Vincentian priest, arrived as a missionary in the area that is now Eritrea and northern Ethiopia. He preferred to employ the local liturgical rite in the Ge'ez language rather than the Roman rite in Latin. He attracted a considerable number of local priests and laity to enter into full communion with the Catholic Church. He died in 1860 at Halai, near Hebo, in what is now the Southern Administrative Region of Eritrea.
