The Error: an overly strong focus on the dignity of man coupled with an over-emphasis on the natural virtues (as opposed to the supernatural virtues of Faith, Hope, and Charity which come from God alone rather than nature). This ignores original sin and the need for supernatural grace, leading to a sort of Utopianism that sees peace as possible without recognizing the Kingship of Christ, and seemingly gives the Church a new mission: peace on earth rather than the salvation of souls. This attitude, and teachings rooted in it, contradict Pope Pius X’s "Quas Primas’’, Pope Leo XIII’s "Testem Benevolentiae Nostrae,’’ ‘‘Rerum Novarum,’’ Pope Pius X’s ‘‘Notre charge apostolique,’’ and other papal and conciliar documents that deal with social teaching.
The Truth: There is no peace without the Prince of Peace. Man has lost his likeness to God through original sin, and this likeness can only be restored through supernatural grace. Without this likeness, there will be strife among peoples and nations, and no amount of “Can’t we all just get along?” thinking can overcome it. The purpose of the Church and all Her laws is the salvation of souls. Peace on earth is a fruit of man’s regaining his likeness to God through the Sacraments and faith, but not the Church’s primary goal.
