Finding, like Michael Davitt, in the doctrine of Henry George an outcome and a confirmation of the principle laid down in 1848 for the liberation of Ireland by Finton Lalor, Dr.M'Glynn threw himself ardently into the advocacy of that doctrine,--so ardently that in August 1882 the Prefect of the Propaganda, Cardinal Simeoni, found it necessary to invite the attention of Cardinal M'Closkey, then Archbishop of New York, to speeches of Dr.M'Glynn, reported in the _Irish World_ of New York, as "containing propositions openly opposed to the teachings of the Catholic Church." It did not concern the Propaganda that these propositions ran on all-fours with the policy of the Irish Land League established by Mr.
Davitt, and accepted by Mr.Parnell.What concerned the Propaganda in the propositions of Dr.M'Glynn at New York in 1882 was precisely what concerns the Propaganda in the programme of Mr.Davitt as mismanaged by Mr.Dillon in Ireland in 1888--the incompatibility of these propositions, and of that programme, with the teachings of the Church.
Upon receiving the instructions of the Propaganda in August 1882, Cardinal M'Closkey sent for Dr.M'Glynn, and set the matter plainly before him.

Dr.M'Glynn professed regret for his errors, promised to abstain in future from political meetings, and begged the Cardinal to inform the authorities at Home of his intention to walk more circumspectly.

The submission of Dr.M'Glynn was approved at Rome, but it was gently intimated to him that it needed to be crowned by public reparation for the scandal he had caused.

He disregarded this pastoral hint, and when the Archbishop Coadjutor of New York, Dr.Corrigan, went to Rome in 1883 to represent the Cardinal, who was unequal to the journey, he found the Propaganda by no means satisfied with the attitude of Dr.M'Glynn.

Two years after this, in October 1885, Cardinal M'Closkey died, and Dr.Corrigan succeeded him as Archbishop of New York.
Between the first admonition given to the sacerdotal ally of Mr.George in 1882 and this event much had come to pass in Ireland.
