143. Vespers—Sunday
               | 
            
            
              {248} 
                Lucis Creator optime. | 
            
            
               
                FATHER of Lights, by whom each day | 
            
            
              |     Is kindled out of night, | 
            
            
              | Who, when the heavens were made, didst lay | 
            
            
              |     Their rudiments in light; | 
            
            
              | Thou, who didst bind and blend in one | 
            
            
              |     The glistening morn and evening pale, | 
            
            
              | Hear Thou our plaint, when light is gone, | 
            
            
              |     And lawlessness and strife prevail. | 
            
            
               
                Hear, lest the whelming weight of crime | 
            
            
              |     Wreck us with life in view; | 
            
            
              | Lest thoughts and schemes of sense and time | 
            
            
              |     Earn us a sinner's due. | 
            
            
              | So may we knock at Heaven's door, | 
            
            
              |     And strive the immortal prize to win, | 
            
            
              | Continually and evermore | 
            
            
              |     Guarded without and pure within. {249} | 
            
            
               
                Grant this, O Father, Only Son, | 
            
            
              |     And Spirit, God of grace, | 
            
            
              | To whom all worship shall be done | 
            
            
              |     In every time and place. |
