(CNN) — Cardinal Keith O'Brien of Scotland, who has been dogged by allegations he abused four men studying to be priests in the 1980s, said in a statement Sunday that "there have been times that my sexual conduct has fallen below the standards expected of me as a priest, archbishop and cardinal."
O'Brien, who resigned last month, did not explicitly state what he had done or what allegations against him are true. "In recent days certain allegations which have been made against me have become public. Initially, their anonymous and non-specific nature led me to contest them," he said in the statement.
He apologized "to those I have offended" and to "the Catholic Church and people of Scotland."
