We explained why our Saviour chose the Sunday for his Resurrection, whereby he conquered death and proclaimed life to the world.

[…] By selecting it now for the commencement of the new life which he graciously imparts to man, he would show us that Easter is the renewal of the entire creation.

Not only is the anniversary  of his glorious Resurrection to be, henceforward, the greatest of days, but every Sunday throughout the year is to be a sort of  Easter, a holy and sacred day.

The Synagogue, by God’s command, kept holy the Saturday or the Sabbath in honour of God’s resting after the six days of the creation.

But the Church, the Spouse, is commanded to honour the work of her Lord.

She allows the Saturday to pass – it is the day on which her Jesus rested in the sepulchre.

But, now that she is illumined with the brightness of the Resurrection, she devotes to the contemplation of his work the first day of the week.

It is the day of light, for on it he called forth material light (which was the first manifestation of life upon chaos), and on the same, he that is the ‘Brightness of the Father,’ (Heb. 1:3) and ‘the Light of the world,’ (Jn 7:12) rose from the darkness of  the tomb.

Let, then, the week with its Sabbath pass by. What we Christians want is the eighth day, the day that is beyond the measure of  time, the day of eternity, the day whose light is not intermittent  or partial, but endless and unlimited.

[…] It was, indeed, right that man should keep, as the day of his weekly and spiritual repose, that on which the Creator of the visible world had taken his divine rest.

But it was a commemoration of the material creation only.

The Eternal Word comes down in the world that he has created.

He comes with the rays of his divinity clouded beneath the humble veil of our flesh.

He comes to fulfil the figures of the first Covenant.

Before abrogating the Sabbath, he would observe it as he did every tittle of the Law.

He would spend it as the day of rest, after the work of his Passion, in the silence of the sepulchre.

But, early on the eighth day, he rises to life, and the life is one of glory.

[…] And rightly was the seventh changed into the eighth, because we Christians put our joy in a better work than the creation of the world….

Let the lovers of the world keep a Sabbath for its creation. But our joy is in the salvation of the world, for our life, yea and our rest, is hidden with Christ in God.
