We get our word “Inspired” from the Greek word εμπνεώ which means “breathed in”. God Himself guided the authors by the action of the Holy Spirit breathing His inspiration into the hand of the authors of Sacred Scripture. Although God is the principle author of Scripture, the human authors are also true authors because they acted as free, subordinate, intelligent instruments of the Holy Spirit guiding them.
Reading Sacred Scripture is in a way much like receiving the Holy Eucharist. In both cases the Word of God comes directly to us. “Number 103” in the Catechism of the Catholic Church tells us the Church has always venerated Sacred Scripture as she venerates the Lord’s Body.
2 Thessalonians ch. 2: v:15 reminds us to hold firm not only to Sacred Scripture but Sacred Tradition as well. Sacred Tradition has been passed down either by word of mouth or by the written word. “So brethern, stand firm and hold tight to the traditions taught by us, either by word of mouth or by letter.” Sacred Scripture and Sacred Tradition form one source from which the Word of God comes to us.
“Infallible” means the Church cannot teach error in matters of faith. Christ Jesus intercedes for us through the power of the Holy Spirit. When we state that the Pope is “Infallible” we mean he can make no mistakes in matters of faith alone. This does not mean the Pope is sinless. Only Christ Jesus and our Blessed Mother are sinless. This is why we call our Blessed Mother the Immaculate Conception. She was born without Original Sin. Christ Jesus came to us in a pure vessel and this vessel was Mary of Nazareth. The Holy Spirit overshadowed our blessed Mother. This was one of the greatest miracles given to the human family. Christ Jesus “tabernacled” among us. Tabernacle is a greek word which means “pitched His tent” among us. So whenever you walk into a Catholic Church you will always see the Tabernacle as the major focal point. We then are reminded that Christ Jesus has “pitched His tent” among us, His children. Pretty nifty, ehh!
