CUF also now has a blog, which I'll be adding to my sidebar.
There is an interesting entry today by Leon Suprenant, who once studied to be a priest, but found that was not the vocation to which he was called. I would encourage anyone considering a vocation to see the method he used for making his final discernment. Discernment doesn't end with a trip to the seminary or to the convent. It ends with ordination, or final vows. Finding you are not called to the priesthood or religious life after you enter such a serious phase of discernment is nothing for which you should hold your head in shame.
Whether you are discerning yourself and struggling, or if you are a parent, friend or relative of someone discerning, there are some good things to learn from Leon's post: Vocation Awareness
Another entry by Leon which caught my eye was on Lent called: Give it up! Read it to see just the many ways we try to get around those bodily penances.
