Career
In 1838 he became guardian at Baden. In 1845 superior and parish priest at Chur. In 1857 definitor, and in 1860 vicar-general of the Diocese of Chur.
After the Sonderbund war, the Radical party opposed Catholic interests.
In consequence of his defence of the Church, Father Theodosius fled to Alsace in 1841. In August of the same year he returned.
In the Capuchin church at Altorf on 16 October 1844, the first three sisters received the habit of the Third Order of Saint Francis. In the meantime Father Theodosius was himself busy as a schoolmaster.
He superintended the people"s schools (Volksschulen), which are attended by others besides the poor.
He promoted continuation schools and was in favour of technical instruction for apprentices and workmen. To stir up anew Catholic life he engaged in popular missions and retreats for priests. The institution of the annual conference of the Swiss bishops was largely due to his efforts.
To bring Swiss Catholics together to strengthen Catholic feeling, and to organize social works, he founded the Pius Society.
He was very keen upon the care and inspection of the helpless and dependent, such as boarded-out children, apprentices, neglected children, and discharged prisoners. With regard to the labour question Father Theodosius expressed himself in his speech at Frankfort in 1863.
In demanding the Christianizing of industry, trade unions, and workmen"s cr banks, he said:
"Formerly monasteries were turned into factories, now factories must become monasteries, and the profits must be shared with the workers". Factories were established to carry out this idea, but they failed, owing to a lack of business capacity in the founders.
At Ingenbohl Father Theodosius founded a printing and book-binding establishment and a society for the distribution of books
