t least he was ready to meet their
leaders, to address them, and to discuss difficult problems with them.
His addresses on the reunion of the Churches, delivered at the Bonn
Conference of 1872, show that he was by no means hostile to the newly
formed communion, in whose interests these conferences were held. In
1874 and again in 1875, he presided over the Reunion Conferences held at
Bonn and attended by leading ecclesiastics from the British Isles and
from the Oriental Church, among whom were Bishop Christopher Wordsworth
of Lincoln; Bishop Harold Browne of Ely; Lord Plunket, archbishop of
Dublin; Lycurgus, archbishop of Syros and Tenos; Canon Liddon; and
Professor Ossinine of St Petersburg. At the latter of these two
conferences, when Dollinger was seventy-six years of age, he delivered a
series of marvellous addresses in German and English, in which he
discussed the state of theology on the continent, the reunion question,
and the religious condition of the various countries of Europe in which
the Roman Catholic Church held sway. Not the least of his achievements
on this occasion was the successful attempt, made with extraordinary
tact, ability, knowledge and perseverance, to induce the Orientals,
Anglicans and Old Catholics present to accept a formula of concord,
drawn from the writings of the leading theologians of the Greek Church,
on the long-vexed question of the Procession of the Holy Spirit. This
result having been attained, he passed the rest of his days in
retirement, emerging sometimes from his retreat to give addresses on
theological questions, and also writing, in conjunction with his friend
Reusch, his last book, _Geschichte der Moralstreitigkeiten in der
romisch-katholischen Kirche seit dem sechzehnten Jahrhundert mit
Beitragen zur Geschichte und Charakteristik des Jesuitenordens_
(Nordlingen, 1889), in which he deals with the moral theology of St
Alfonso de' Liguori. He died in Munich, on the 14th of January 1890, at
the age of ninety-one. Even _in articulo mortis_ he refused to receive
the sacraments from the parish priest at the cost of submission, but the
last offices were performed by his friend Professor Friedrich.
