Invatamintul teologic al Bisericii Ortodoxe Romane din Banat, isi aseaza inceputul in perioade indepartate. De la forme simple de pregatire si calificare a slujitorilor bisericesti-preoti si cantareti s-a ajuns, in anul 1822, la intemeierea Scolii Clericale din Virset, cu predare si in limba romana, unde au activat personalitati marcante ale vietii spirituale si culturale romanesti: Andrei Saguna, Nicolae Tincu Velia, Ignatie Vuia.
In anul 1865, odata cu reinfiintarea Mitropoliei Ardealului de catre ierarhul Andrei Saguna, a fost reactivata si Episcopia Caransebesului. In acelasi an se transfera aici si sectia romaneasca a scolii clericale din Virset, care, in prima forma, functioneaza ca Institut Teologic Diecezan, pe langa acesta, intemeindu-se in 1876 o sectie pedagogica, devenita in 1894, Scoala Normala de Stat.
Institutul Teologic se transforma in anul 1927 in Academie Teologica, functionand in aceasta organizare pana la reforma invatamantului din 1948. Datorita situatiei politice din acea perioada, invatamantul teologic din Caransebes se reduce dupa aceasta perioada doar la o Scoala de Cantareti Bisericesti, ridicata in anul 1955 la gradul de Seminar Teologic cu cinci ani de studiu.
Dupa anul 1993, scoala a fost integrata in reteaua invatamintului de stat, devenind Seminarul Teologic Liceal Ioan Popasu. Intre anii 1993-1996, pe langa Seminar a functionat si Scoala Postliceala de cantareti bisericesti si invatatori, iar din 1993 a fost reactivata Scoala de cantareti bisericesti.
Invatamantul teologic din Caransebes a stat permanent sub indrumarea ierarhilor acestei eparhii, ei insasi remarcabile personalitati teologice si culturale:
Un merit important in istoria acestei scoli revine profesorilor care s-au straduit permanent cu formarea viitorilor slujitori ai altarelor:
Prin stradaniile dascalilor Scolii Teologice din Caransebes, s-au format zeci de generatii de tineri care au devenit slujitori ai bisericii in tara si strainatate (Europa de Vest, Serbia, SUA, Ungaria), cadre didactice universitare si seminariale:
Din anul 1998, la Caransebes functioneaza si sectia de Teologie Ortodoxa - Istorie, afiliata Universitatii Eftimie Murgu din Resita, in cadrul careia se pregatesc atat viitorii slujitori ai altarelor strabune, cat si cei ce vor preda istoria bimilenara a patriei noastre.
The beginnings of the theological education as part of Romaina Orthodox Church from Banat are lost in the darkness of time. Several schools for preparation of servants of the Church are known, such as the one that existed near St. George monastery from Caransebes.
Systematic, theological education starts in 1892 when a Clerical School with a romanian section was founded in Virset. When the Diocese of Caransebes was reactivated in 1865, this section was removed here and entrusted to the care of His Holiness Bishop of Caransebes. The school worked first as Diocese Theological Institute - including a pedagogical section. In 1927 The Theological Institute was changed into The Theological Academy, that worked until 1948,when the political situation of Romania changed. Until 1955 there was only a school for church chanters, which, afterward became the Theological Seminar with five years of studies, graduates becoming priests in rural parishes. 1n 1993, The Seminar Ioan Popasu entered the educational network of state as a secondary school.
After 50 years of absence, the tradition of academic, theological education in Caransebes was reestablished. In 1998, a Faculty of Orthodox Theology - History was created as a section of Eftimie Murgu University from Resita. It has four years of studies.
From the inauguration of the The inauguration of the theological courses in 1865 until now, the theological education was under the guidance of bishops as Ioan Popasu (1865-1889), the true promotor of the cultural establisments and founder of both Institutes (theological and pedagogical), Nicolae Popea (1889-1908), Ilie Miron Cristea (1910-1919), who became the first Patriarh of Romania. Between 1962-1994, the Theological Seminar was under the leadership of His Beatitude Nicolae Corneanu, Metropolitan of Banat, but, after reactivation of the Diocese of Caransebes, it came back under the leadership of local bishops, Emilian Birdas (1994-1996) and his Holiness dr. Laurentiu Streza (from 1996).
In the history of this school a great merit belongs to all headmasters and rectors: Filaret Musta, dr. Iuliu Olariu - a great theologian and a real pioneer of romanian biblical thology, dr. Petru Barbu and others. Actual headmaster of The Theological Seminar is Father Ionel Popescu.
To these we must add the names of prestigious professors that taught in our school: dr. Vasile Loichita, dr. George Popovici - member of the Romanian Academy, who wrote many theological and historical works, dr. Iova Firca, Antoniu Sequens - the creator of a rich repertory for the church and lay choirs, dr. Petru Rezus - the editor of The Banat Altar review and a great dogmatist, dr. Mircea Chialda who let us a massive work about The Sacrifices of the Old Testament, dr. Silviu Anuichi, dr. Sorin Cosma - the author of the doctoral thesis with the title: The temperance in the Ancient Philosophical Ethics and in Christian Morals. A test of Christian Sophrology (1997), dr. Nicolae Achimescu.
Graduates of this Seminar with doctoral courses in our country or abroad are now great personalities in Romanian Ortodox Church: dr. Remus Rus - professor of theology at Bucharest, dr. Aurel Jivi - at Sibiu Faculty of Theology, dr. Ioan Sauca - the spokesman of the Romanian Ortodox Church at the World Council of Churches.
Nowadays teaching staff (clery or lay) are called to keep the tradition of training personalities who can increase the prestige of this venerable theological school.
