His father was a direct descendant of Theodoricus de Raupena, the eldest brother of Bishop Albert who founded the city of Riga in 1201.

He traveled back to Saratov in 1904 to co-consecrate his successor as bishop of Tiraspol Josef Alois Kessler on 10 November.

[8] In early 1902, Bishop Stefan Aleksander Zwierowicz was exiled to Tver for issuing a ban on Catholics sending their children to Orthodox schools.

[9] Bishop Ropp issued directives facilitating conversion, including conducting religious instruction in the language of the faithful.

[11] However, he soon purchased Kurier Litewski from Feliks Zawadzki, merged the editorial staff of his newspaper into it, and continued publishing under that title.

His goal was to ease Polish-Lithuanian tensions related to the struggle over the auxiliary language of worship in mixed parishes.

[15] The official reasons cited were his political activities, disregard for Russification policies, and "narrowly nationalistic efforts aimed at Polonizing Lithuanians and Belarusians.

[16] He returned to Saint Petersburg to take up this post, and, following the February Revolution, Archbishop Ropp, decreed that all his priests would take a role in organizing a Christian Democratic Party to participate in the planned Russian Constituent Assembly in order to defend the rights of the Catholic Church in Russia.

In 1919, he was arrested during the Red Terror by the CHEKA and received a death sentence for anti-Soviet agitation,[17] but was instead deported to the Second Polish Republic in 1920 on the intercession of the Holy See.

[21] He spent the last months of his life with his nephew, Stefan Ropp, the director of the Poznań Trade Fair.

[17] On March 21, 1983, his coffin was transferred to the Pro-Cathedral in Białystok, which at the time served as the seat of the apostolic administration for the Polish part of the Archdiocese of Vilnius.
