He was born on 14 April 1901 in Prudnik in the German Empire, as a son of Franciszek and his wife Maria.

[1] He was probably a relative of a Franciscan Gotthard Wojaczek (1872–1931), buried in the monastery cemetery at the church of St. Joseph in Prudnik.

Thanks to the financial help he had received from his family, he left Prudnik and moved to Bavaria, where he entered the religious Congregation of the Missionaries of Mariannhill.

After graduating from the religious gymnasium, based on the order of the school management, he went to further studies in the Netherlands, where he practiced in a monastery.

On the recommendation of the Superior General, he left the monastery and went to Altdorf in Switzerland, where he worked for two years as a history, Latin and religious teacher at the local school.

He found the body of Father Jerzy Greiner, murdered by the Russians in the basement of the presbytery in Skorogoszcz.

[1] For local representatives of the state authorities, Father Wojaczek was suspicious, especially because of his contacts with the religious headquarters located abroad.
