His first pastoral appointment was a curate at Kilbrittain, County Cork from October 1883 to January 1884. He briefly resumed his post-graduate studies at St Finbarr's Seminary (now College), Cork from January to November 1884. His second curacy was at Tracton, County Cork from November 1884 to September 1896.

Cohalan was an outspoken critic during the Irish War of Independence, condemning acts of violence on both sides. In particular, he denounced the policy of reprisals. In July 1920, he pronounced an interdict on the killers of an RIC sergeant, shot dead in the church porch in Bandon. He declared that anyone killing from ambush would be excommunicated. On 12 December 1920, Cohalan, issued a decree saying that "anyone within the diocese of Cork who organises or takes part in ambushes or murder or attempted murder shall be excommunicated". In turn, his life was threatened by the IRA. In August 1928, he condemned the British government which had allowed Terence McSwiney to die on hunger-strike in 1920.
