The Sundays in Lent are generally termed from their number, being called the first, second, &c. Sunday in Lent. But the fourth Sunday is sometimes called Mid-Lent Sunday; and the fifth Sunday is called Passion Sunday; though this name might perhaps be more properly applied to the following Sunday, which is the Sunday next before Easter, and which has obtained the appellation of Palm Sunday, in commemoration of our Saviour’s triumphal entry into Jerusalem, when the multitide that attended him strewed palm branches in his way.
Sunday being a Festival, the Church allows us to interrupt our Fasts on the Sundays in Lent; but it is still her earnest desire to keep us in mind of the solemn duties which are appropriate to the season. Accordingly, in the Epistles for the first three Sundays, we are taught the necessity of mortifying our sinful passions. The Epistle for the fourth Sunday shows, by a striking allegory, the superior excellence of that covenant, which CHRIST by his death sealed, over the law of Moses. The Epistle for the fifth Sunday points out to us the divine purifying efficacy of the blood of CHRIST. And the Epistle for the Sunday next before Easter exhorts us to humility, from the consideration of the infinite condescension of the Son of GOD in submitting, for our sakes, to the death of the cross. The Gospel for the first Sunday, to animate us to resist temptation, recites the history of CHRIST’S temptation in the wilderness. The Gospels for the four following Sundays, with a view to excite us to the imitation of the benevolence of CHRIST, and to confirm our faith in him, set before us some striking instances of his divine compassion and power, and of that forcible reasoning whereby he vindicated his divine claims. The Gospel for the Sunday next before Easter commences the recital of the sufferings of CHRIST, which the ensuing week more particularly commemorates.
