Thankfully, our Western culture is built around the foundational idea of the dignity of man. This thought informs our laws and our practice. We think that murder is wrong. We think that individuals have rights that should not be violated. We think that each person should be able to do or become whatever he wishes to be.
It is probable that most people that read this question in the catechism in 2016 zoom in on the words “in six days.” So let me say from the beginning that it is OK for believers to disagree on how the word day should be interpreted. Some hold to a literal 24 hour day and others think day represents a much longer period of time.
God created the world we see around us (including us). God also cares about that world. God cared enough to send Jesus so that in the end, Jesus can fix all the the things we’ve broken.
There is nothing that happens in the world that takes God by surprise. When our first parents rebelled against God by eating the fruit, God had a plan already in place to send Jesus to fix the resulting mess.
The importance of a proper understanding of the trinity is highlighted when we think of love as a characteristic of God. Love implies an other to love. God did not create humanity because without us, he would not have been able to demonstrate love.
Christianity believes (because the Bible declares) that there is only one God. And as we learned yesterday in Question 4, there are specific things to be believed about that one God as revealed in the Bible.
