It is no less unquestionable that, in doing all we can to bring about the re-establishment of Christ's kingdom, we will be working most effectively toward a lasting world peace. Pius X in taking as his motto "To restore all things in Christ" was inspired from on High to lay the foundations of that "work of peace" which became the program and principal task of Benedict XV. These two programs of Our Predecessors We desire to unite in one - the re-establishment of the Kingdom of Christ by peace in Christ - "the peace of Christ in the Kingdom of Christ."<ref>http://w2.vatican.va/content/pius-xi/en/encyclicals/documents/hf_p-xi_enc_19221223_ubi-arcano-dei-consilio.html</ref> | In Ubi Arcano, the Pope wrote: "It is, therefore, a fact which cannot be questioned that the true peace of Christ can only exist in the Kingdom of Christ - "the peace of Christ in the Kingdom of Christ."
