This is a silly idea. This is why:
1) Catholic Blogging is a form of evangelisation
2) Catholic Blogging (or even Lutheran or Anglican or Orthodox blogging–let’s get ecumenical here) is (again, as the Lutherans say) a form of “mutual consolation of the brethren”
3) Blogging for the sake of the gospel is a way of using a spiritual gift (did not St Paul say “…and to some it is given to be bloggers”?)
So all up, that makes blogging a “work of mercy” doesn’t it? What sense is there in giving up such a worthy causes for Lent?
Of course, blogging can be done out of a motivation of pride. But hate the sin and love the blog, I say.
And in any case, where in canon law does it say Lent has to be boring?
Give up blogging for Lent? Not this little black duck.
