127 Therefore, let us all enter into closest union with Christ and strive to lose ourselves, as it were, in His most holy soul and so be united to Him that we may have a share in those acts with which He adores the Blessed Trinity with a homage that is most acceptable, and by which He offers to the eternal Father supreme praise and thanks which find an harmonious echo throughout the heavens and the earth, according to the words of the prophet, "All ye works of the Lord, bless the Lord." Finally, in union with these sentiments of Christ, let us ask for heavenly aid at that moment in which it is supremely fitting to pray for and obtain help in His name. For it is especially in virtue of these sentiments that we offer and immolate ourselves as a victim, saying, "make of us thy eternal offering."
