He and his wife Pauline(Nee Bacmeister) laid the foundations for the Evangelical parish and Anandapur, a village made out of jungle in the interior of Karnataka.
One of his pioneering works was the publication of the first Kannada newspaper, Mangalooru Samachara (meaning Mangalore News).
In the days of Mögling's career at Mangalore, there was no simple way of communicating news and other items to the general public because of non-existence of a medium like radio and of a newspaper in the native language.
He decided to publish a Kannada newspaper with the intention of spreading news items to the public.
[1][11] The newspaper became popular and it was decided to shift its publication to the city of Bellary where it was renamed as Karnataka Samachara.
He also published a German book titled Das Kurgland which mainly deals with his activities related to Christianity.
[1] He also composed about 20 poems (along with Weigle who was his cousin brother and a fellow Basel Missionary) in modern Kannada poetical form.
[1] Mögling was helped in this venture by a philanthropist, J Casamajor who was a retired judge from Chennai and settled in Nilgiris.
[1] With an exchange of letters, the two discussed on ways to collect Kannada manuscripts, select the important ones among them for publishing and identifying skilled people who would be needed to complete this activity.
The largest published title running 760 pages was the Basava Purana and the smallest one was Kanakadasa's Haribhaktasara.
[1] Other titles published as a part of Bibliotheca Carnataca were Dasara Padagalu (a collection of 170 Haridasa songs) and Lakshmisha's Jaimini Bharata.
This venture met an abrupt end due to the sudden demise of Casamajor and Mögling's return to Germany.
After getting an approval for his scheme from the Madras Province's Education Department, Mögling published this entire book in his devised orthography.
This seminary was established to train Pastors for the Protestant churches in Karnataka and Malabar areas.
