Ukelele Ike, here’s an example of the use of reason in theology. In all the debate about the EO, you may be hearing references to Matthew 25. The relevant passage is:
[QUOTE=Matthew 25]
34 “Then the King will say to those on his right, ‘Come, you who are blessed by my Father; take your inheritance, the kingdom prepared for you since the creation of the world. 35 For I was hungry and you gave me something to eat, I was thirsty and you gave me something to drink, I was a stranger and you invited me in, 36 I needed clothes and you clothed me, I was sick and you looked after me, I was in prison and you came to visit me.’
37 “Then the righteous will answer him, ‘Lord, when did we see you hungry and feed you, or thirsty and give you something to drink? 38 When did we see you a stranger and invite you in, or needing clothes and clothe you? 39 When did we see you sick or in prison and go to visit you?’
40 “The King will reply, ‘Truly I tell you, whatever you did for one of the least of these brothers and sisters of mine, you did for me.’

Now, if you are a Christian, you have to take this passage seriously. It’s Jesus telling a parable that has obvious moral intent.
But what does it mean in today’s world? How should Christians react to that passage today? Answering those questions calls for the use of reason, in analyzing the passage and the scope of its implications.
For example, was Jesus meaning this parable as a direction of some sort just to individuals, as a moral commandment for individuals to care for others? or is it a direction for individuals to implement through their society (i.e. government)?
And in this parable, there does not appear to be any risk to the righteous for carrying out this duty to visit the imprisoned. Does that mean the parable has less value as a direction if there is a clear risk to the righteous for doing so? or to their families and friends? or should the possibility of risk simply increase the moral imperative of that parable, to take pity on the detained even if there is personal risk to you, your friends and family, or your society?
And is this passage simply urging good care for detained people, or does it go further and call for action to help people who are wrongfully detained?
This passage thus serves as the jumping off point for a major theological and moral exegesis, in which reason plays a key role. There will be different interpretations of how this passage applies to current events.
(Note that I’m giving an example that has current application, but I’m not meaning this post to be a comment on the merits of the EO; just using it to show how a passage from the Gospels can be used by Christians for moral guidance, with the assistance of reason, in grappling with today’s moral issues.)
