Freemasonry was condemned by Clement XII. in 1738. In the constitution /In eminenti/, in which this condemnation was promulgated, he explained the reasons that induced him to take this step. These were the anti-religious tendencies of the society both in its theory and practice, the oaths of secrecy and obedience to unknown superiors, and the danger to Church and State involved in such secret combinations. This condemnation has been renewed by several of his successors, as for example Benedict XIV. (1751), Pius VII. (1821), Gregory XVI. (1832), Pius IX. (1865), and Leo XIII. (1884). Since 1738 Catholics have been forbidden under penalty of excommunication to become members of the society or to promote its success. According to the constitution /Apostolicae Sedis/ (1869), which is in force at the present time, excommunication is levelled against those who join the Freemasons or similar bodies that plot against the Church and established authority, as well as against those who favour such organisations and do not denounce their leaders.

From its foundation by St. Ignatius of Loyola and its approval by Paul III. the Society of Jesus had remained true to the teaching and spirit of its holy founder and loyal to the Holy See. In the defence of the Church, especially in Germany, Austria, Poland, Hungary, and France, in the domain of education and of literature, in the work of spreading Christianity amongst the races and peoples in India, China, Japan, and America, the Jesuit Fathers took the foremost place. They laboured incessantly to stay the inroads of heresy, to instil Catholic principles into the minds of the rising generation, and to win new recruits to take the place of those who had gone over to the enemy.
