In his First Letter to the Corinthians, Paul promises us that God's foolishness is wiser than human wisdom. There are many things in our faith that do not make sense at first pass, such as the mystery of the Eucharist, but we can study and learn and thus deepen our faith by understanding it better. Reason enhances faith, it does not oppose it, but not without spending time learning.
Based on 1 Corinthians 1:17-25:
For Christ did not send me to baptize but to proclaim the gospel, and not with eloquent wisdom, so that the cross of Christ might not be emptied of its power.
For the message about the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God. For it is written,
‘I will destroy the wisdom of the wise,
and the discernment of the discerning I will thwart.’
Where is the one who is wise? Where is the scribe? Where is the debater of this age? Has not God made foolish the wisdom of the world? For since, in the wisdom of God, the world did not know God through wisdom, God decided, through the foolishness of our proclamation, to save those who believe. For Jews demand signs and Greeks desire wisdom, but we proclaim Christ crucified, a stumbling-block to Jews and foolishness to Gentiles, but to those who are the called, both Jews and Greeks, Christ the power of God and the wisdom of God. For God’s foolishness is wiser than human wisdom, and God’s weakness is stronger than human strength.
