First maxim--"I had the fear of God as the guide of my way through Gaul and Italy, and also in the islands, which are in the Tyrhene Sea."[105] The second maxim--"From the world ye have gone to Paradise." This saying is taken from the Epistle to Coroticus, in which the Saint after bewailing his slaughtered neophytes, yet rejoices that it happened after they believed, and were baptized; for then they merely left this world to go to Paradise. In course of time this appears to have been adopted in Ireland as a consoling thought for the survivors that their deceased friends had gone from this world to Paradise--"De seculo recessistis ad Paradisum." Third maxim--"Deo Gratias"--thanks be to God. It was always on the lips of St. Patrick--whether the news was good or bad, pleasing or displeasing, the same word was there--"Deo Gratias." The fourth maxim--"O Church of the Scots--nay of the Romans--as ye are Christians, be ye also Romans." That is, as ye are Christians, and bound to obey Christ, so be ye also Romans, obedient to the See of Rome. Maxim the fifth--"At every hour of prayer it is fitting to sing that word of praise--'Lord have mercy on us, Christ have mercy on us.' Let every Church which follows me sing--'Kyrie Eleison, Christe Eleison, Deo Gratias.'" It would seem that the 'Kyrie Eleison' at the beginning of Mass, and the 'Deo Gratias' at the end of Mass were not at that early period universally chanted in the public liturgy. Hence the Saint, who seems to have a special love for these two brief and fervent expressions of pardon and thanksgiving, made it a rule that they should be sung in the liturgy of all the Churches which he founded in Ireland. The practice has since become obligatory throughout the universal Church. VIII.--THE TRIPARTITE LIFE OF ST. PATRICK. The earliest memoir of St. Patrick was perhaps the Metrical Life by St. Fiacc of Sletty, to which we have already referred. Of the Life of St. Patrick in the _Book of Armagh_ we shall speak in the next chapter. But what is called the "Tripartite Life" of the Saint is, as far as we can judge, if not the earliest, certainly the fullest and most authentic account of our national Apostle now extant.
