They were discovered by reporters at the news website Utero.pe, which found that Peru's cardinal had lifted texts from Paul VI and Benedict XVI.
The daily El Comercio newspaper issued a statement on the matter after it removed two of Cipriani's articles: "Upon detection of plagiarism committed by Cardinal Juan Luis Cipriani in various collaborations with El Comercio newspaper, after giving the daily's position on what was explained by the Cardinal, it proceeded to remove his two articles contained on its website," El Comercio wrote.
"The move has aroused the suspicion of some people in networks that it was taken with the intention of concealing the aforementioned texts."
"This is not so," El Comercio wrote, explaining that the newspaper does not publish primary articles with content actually written by tertiary sources.
"It is clear that the newspaper will not publish more articles of the cardinal," El Comercio concluded.
The conservative 71-year-old cardinal apologised on a radio programme and asked listeners to "pray that we pastors are always true to the teachings of the church".
