What is this Invocabit Thing?

The term "Invocabit" refers to the first Sunday in Lent in the liturgical calendar, traditionally observed by the Western Church. The name itself derives from the Latin invocabit, meaning "he will call," which is the first word of the Introit for this day, taken from Psalm 91:15: "He will call upon Me, and I will answer him." This day marks the beginning of the penitential season of Lent, a period of preparation for the celebration of the Resurrection at Easter.

The history of Invocabit in the Church is tied to the ancient practices of fasting, prayer, and repentance during Lent, which were intended to imitate the forty days of fasting and temptation that Christ experienced in the wilderness. The observance of this day is ancient, with early evidence of its celebration appearing as early as the fourth century. In the early Church, Lent was a time for catechumens—those preparing for baptism—to undergo intensive instruction, prayer, and penance. Invocabit, as the first Sunday, set the tone for this season of spiritual renewal and purification.

The traditions surrounding Invocabit are rich in liturgical elements. In the medieval period, the liturgical color for the day was purple, symbolizing penitence and the royal dignity of Christ, who alone has the power to call and save. The Introit, Invocabit me, highlighted the theme of God’s promise to hear the prayers of the faithful, a fitting introduction to the Lenten journey of reflection and prayer. The Scripture readings for the day focus on God's faithfulness and His willingness to rescue those who call upon Him, as seen in the psalms and other texts, reinforcing the central theme of God's mercy and the call to repentance.

Theologically, Invocabit emphasizes two main points. First, it underscores the reality of spiritual warfare and temptation, as seen in Christ’s own wilderness temptation, which is often the focus of the Gospel reading on this Sunday. Second, it speaks to the grace of God that responds to the call of the penitent soul, promising to deliver and protect those who trust in Him. The call of the faithful, in the face of their temptations and sins, is met with God's steadfast presence and aid, which is the heart of the Lenten message.

In terms of pastoral application, Invocabit is a reminder to Christians of the importance of repentance, prayer, and fasting, not as acts of self-purification, but as a means of drawing closer to God and acknowledging His mercy. The penitential practices of Lent, which find their expression most fully in the early days of the season, are not only about self-examination and contrition but are rooted in the deeper truth that God is always ready to hear the cries of His people.

In summary, Invocabit serves as a profound reminder that Lent is a season of repentance and renewal, rooted in the trust that God answers the call of His people. The day reminds the Church that as Christ was tempted and tested, so too will the faithful be tested. Yet, in the midst of trial, God’s faithfulness is sure, and His promises are steadfast. The Church’s celebration of Invocabit is both a theological proclamation of divine mercy and a pastoral invitation to engage deeply in the Lenten discipline of prayer, fasting, and repentance.
