I agree! observing Lent would be more appropriate and celebrating Easter...This is a time for Self Reflection to understand the greatest sacrafice done for us..
For God so loved the world, that he gave his one and only Son, that whoever believes in him should not perish, but have eternal life
Last night our priest wished us a happy and joyful Lent -- as well as a prayerful, fasting and almsgiving Lent.
And the Gospel emphasized "when" we do these things!!
Also the Gospel emphasized not looking unkept, gloomy or boastful during Lent as the hypocrites did.
So as your post suggests -- let's celebrate Lent in a joyful and humble way!
