From 1838 to 1845, Father Mathew, the Irish apostle of temperance, administered an abstinence pledge to some three to four million of his countrymen, though his efforts had little permanent effect there, and then starting in 1849 to more than 500,000 Americans, chiefly his fellow Irish Catholics, who formed local temperance societies but whose influence was limited. In 1872 the Catholic Total Abstinence Union of America united these societies and by 1913 reached some 90,000 members including the juvenile, women's, and priestly contingents. The Union pursued a platform of "moral suasion" rather than legislative prohibition and received two papal commendations. In 1878 Pope Leo XIII praised the Union's determination to abolish drunkenness and "all incentive to it," and in 1906 Pope Pius X lauded its efforts in "persuading men to practise one of the principal Christian virtues — temperance." By the time the 18th Amendment was up for consideration, however, Archbishop Messmer of Milwaukee denounced the prohibition movement as being founded on an "absolutely false principle" and as trying to undermine the Church's "most sacred mystery," the Eucharist, and he forbade pastors in his archdiocese from assisting the movement but suggested they preach on moderation. In the end, Catholicism was largely unaffected in doctrine and practice by the movements to eliminate alcohol from church life, and it retained its emphasis on the virtue of temperance in all things.
