For though there are no seasons which are not full of Divine blessings, and though access is ever open to us to God’s mercy through His grace, yet now all men’s minds should be moved with greater zeal to spiritual progress, and animated by larger confidence, when the return of the day, on which we were redeemed, invites us to all the duties of godliness: that we may keep the super-excellent mystery of the Lord’s passion with bodies and hearts purified.
–Saint Leo the Great (c. 400-461)
