How has modernist thinking impact the Mass, the renewal of the Sacrifice of the Cross? Given the importance of subjective human experience in neomodernism, in the field of the Liturgy we can detect a de-emphasis on the Liturgy as the worship of Almighty God in favor of a community celebration of one’s own life experience. After a high of seventy-four percent of Catholics who attended Mass in the United States in the post-WWI era, by 1965, sixty-five percent attended, compared with twenty-five percent in 2000. What is more, the data reveal that only twenty percent of the generation of Catholics born after 1960 attends Mass once per week. One major reason for this decline was the collapse of the Liturgy after the misimplementation of Sacrosanctum Concilium, with the resulting harm to the faithful’s understanding of dogma and morals over time. As the Latin phrase goes, lex orendi, lex credendi!
