Micaela at California to Korea is hosting a link-up called "3 Reasons I love Catholicism." You can submit your link all month. There are lots of good submissions, so check them out and join up. My reasons (in this post, anyway) are the triumvirate of truth, goodness, and beauty. I will show you how truth, goodness, and beauty are essential to the Contemplative Homeschool and to seeking God.
Fr. Benedict Groeschel, in Spiritual Passages: The Psychology of Spiritual Development "for those who seek", uses the categories of truth, beauty, goodness, and oneness in a similar way to learning styles or temperaments. They signify to him four ways of relating to God. We can use these categories to help ourselves and our students/children grow spiritually.
Truth satisfies the intellect
The Catholic Church speaks the truth, no matter how few listen. She does not shy away from controversy. Countless Catholics have been martyrs for the truth. Unlike our relativistic culture, and some other religions and philosophies, Catholics believe the truth is objective and knowable. Humans have minds that desire satisfaction. By upholding objective truth, the Church upholds man's dignity.
