As to those other things which we hold on the authority, not of Scripture, but of tradition, and which are observed throughout the whole world, it may be understood that they are held as approved and instituted either by the apostles themselves, or by plenary Councils, whose authority in the Church is most useful, e.g. the annual commemoration, by special solemnities, of the Lord's passion, resurrection, and ascension, and of the descent of the Holy Spirit from heaven, and whatever else is in like manner observed by the whole Church wherever it has been established.
Near our vineyard there was a pear tree laden with fruit that was not attractive in either flavor or form. One night, when I [at the age of sixteen] had played until dark on the sandlot with some other juvenile delinquents, we went to shake that tree and carry off its fruit. From it we carried off huge loads, not to feast on, but to throw to the pigs, although we did eat a few ourselves. We did it just because it was forbidden.
In no passage of the holy canonical books there can be found either divine precept or permission to take away our own life, whether for the sake of entering on the enjoyment of immortality, or of shunning, or ridding ourselves of anything whatever. Nay, the law, rightly interpreted, even prohibits suicide, where it says, 'Thou shalt not kill.' This is proved especially by the omission of the words "thy neighbor," which are inserted when false witness is forbidden.
In all trouble you should seek God. You should not set Him over against your troubles, but within them. God can only relieve your troubles if you in your anxiety cling to Him. Trouble should not really be thought of as this thing or that in particular, for our whole life on earth involves trouble; and through the troubles of our earthly pilgrimage we find God.
The same divine authority that forbids the killing of a human being establishes certain exceptions, as when God authorizes killing by a general law or when He gives an explicit commission to an individual for a limited time.
Your first task is to be dissatisfied with yourself, fight sin, and transform yourself into something better. Your second task is to put up with the trials and temptations of this world that will be brought on by the change in your life and to persevere to the very end in the midst of these things.
That your enemies have been created is God's doing; that they hate you and wish to ruin you is their own doing. What should you say about them in your mind? "Lord be merciful to them, forgive them their sins, put the fear of God in them, change them!" You are loving in them not what they are, but what you would have them to become.
I too have sworn heedlessly and all the time, I have had this most repulsive and death-dealing habit. I'm telling your graces; from the moment I began to serve God , and saw what evil there is in forswearing oneself, I grew very afraid indeed, and out of fear I applied the brakes to this old, old, habit.
This entire most beautiful order of good things is going to pass away after its measure has been exhausted; for both morning and evening were made in them.
