The word “Eucharist” comes from the Greek word for thanksgiving. In the Catholic faith, we use it to describe the liturgical action whereby we enter into communion with God. Thus, we enter into relationship with God first and foremost by expressing gratitude.
The stain of Original Sin is blindness to the truth that we are made in the image and likeness of God. It is the inability to acknowledge what I recently heard described as our “Original Blessing.” Thus, on a very basic level, our Original Sin is really the offense of ingratitude.
The Ironic Catholic recently posted a video clip that points out one way this Original Sin is still present in the world today (Warning: the language is a little bit rough around the edges, but the message more than makes up for it):
We are called to enter into relationship with God. To give thanks for the reality that all we have is Gift and we already are Blessed and Chosen by the Almighty Father. Until we do, we will always be searching for the forbidden fruit, and will feel cheated by the very fact that it is forbidden!
