Original sentence: Many have claimed that Vatican II went much further in encouraging "active participation" than previous Popes had allowed or recommended.Though popes Pius X, Pius XI, and Pius XII consistently asked that the people be taught how to chant the responses at Mass and that they learn the prayers of the Mass in order to participate intelligently, while for its part, Vatican II never asked for the involvement of the laity in the sanctuary that is typical of postconciliar practice
Edited sentence: Popes Pius X, Pius XI, and Pius XII consistently asked that the people be taught how to chant the responses at Mass and that they learn the prayers of the Mass in order to participate intelligently, while for its part, Vatican II never asked for the involvement of the laity in the sanctuary that is typical of postconciliar practice.While many have claimed that Vatican II went much further in encouraging "active participation" than previous Popes had allowed or recommended, a careful examination of Sacrosanctum Concilium as well as earlier papal writings shows the inaccuracy of this claim
