The removal from the Vatican by Pope Francis was a "bitter personal experience" for him, said the former private secretary of Pope Benedict XVI and Prefect of the Pontifical Household to the Würzburg weekly newspaper "Die Tagespost" (Wednesday Online).
"But I didn't let myself get discouraged and hoped and prayed that one day a new task would be waiting for me. Now it's here. It is very possible that there is divine logic behind the appointment as Apostolic Nuncio, which has utilised papal pedagogy."
He is now looking forward to his new position as nuncio for Lithuania, Latvia and Estonia, "which I also see as a sign of the Pope's trust in me," said the 67-year-old.
In view of the current political situation, the mission represents a "delicate challenge".
Beforehand, he will be travelling to the Vatican in order to receive the necessary information, advice and instructions from the competent authorities, in particular the Secretariat of State.
The Vatican announced Gänswein's appointment as nuncio for the Baltic states on Monday.
A year ago, Pope Francis sent the former private secretary of his late predecessor Benedict XVI back to his home archdiocese of Freiburg. He was not initially given a new role there.
This was preceded by personal disagreements between Francis and Gänswein.
