Today marks the Solemnity of the Immaculate Conception, our celebration of Mary's freedom from original sin from the moment of her conception. In the first reading, we see Adam blame his consumption of the forbidden fruit on Eve, showing the influential power of femininity.
While he's likely attempting to shirk blame, it is certainly true that Eve held influence over Adam! We also see God set the framework for a healthy, righteous relationship between man and woman.
In the second reading, we see Paul lay out for us the many blessings that the Lord has bestowed on humanity, especially His plan for salvation. This is appropriate for today, as that plan is fulfilled in the birth of Jesus from His sinless mother, Mary. Paul also reminds us that we "exist for the praise of His glory."
