Hi!
I hope this helps! Here is the website I got the information from:

What it means to be Blessed.
Up until the beatification of a Servant of God Catholics must observe a strict rule of non cultus, meaning that while they may privately pray to and venerate an individual whom they believe to be in heaven there may not be any public acts of religious veneration. Thus, the rule which the Cause has been so insistent upon - no display of the blessed’s picture in places of worship, no hymns to him and no public prayer directly to him - conforms to the strict norms of the Church in this matter. In fact, the presence of a cultus before the approval of the Church is given can end the candidacy of a Servant of God.
With Beatification a number of marks of veneration can be given to a person. The most important one is that a feast day, with its proper Mass and Office (Liturgy of the Hours), can be granted to particular dioceses and religious orders and congregations. For example, Blessed Kakeri Tekawitha, the Lily of the Mohawks, is celebrated on the liturgical calendars of the U.S. and Canada. In the U.S. and Mexico there is a feast day for Blessed Juan Diego, the visionary of Guadalupe. By analogy, this privilege is somewhat akin to the practice of episcopal canonization earlier in Church history, except that a bishop manifests to Rome his flock’s desire to venerate a Blessed and Rome grants such local veneration.
With beatification comes the restricted right to venerate the relics of the blessed, to have public prayers to him and to honor his images in places of worship where this is granted by the Holy See. It is restricted in the sense that it is the veneration of a part of the Church and not the whole, and lacks the finality of canonization.
¹Cultus. A certain negativity has attached itself to the English term cult (a false, exaggerated religious system) which should not be applied to the older, properly understood, Latin term cultus. The Latin term in the ancient world had the meaning of religious worship of God or a god. It could be applied to the True God (which would be legitimate) or to a pagan god among gods (which would be idolatry). In using the term, but with specific theological meaning, the Church distinguishes between the forms of worship appropriate to God, Trinity, Christ and the Blessed Sacrament (called latria, worship or adoration, in the strict sense), and the forms of veneration and honor appropriate to the Blessed Virgin, the angels and the saints (called hyperdulia or the greatest measure of veneration in the case of Mary and dulia or simple veneration in the case of the angels and other saints). It is a principle of justice that we must honor, respect and show gratitude in proper measure to those who are part of God’s plan for our natural and supernatural life. God commands it in the Fourth Commandment. This includes our natural parents who gave us life, but also those to whom we owe a debt for their role in the redemption (1 Cor 4:14-16, Heb. 13:7), first among whom is the Blessed Virgin Mary (Lk 1:48).But without the fidelity of the angels, who served as God’s messengers, of the prophets, of the apostles, the evangelists, the Fathers and the great and holy men and women of all ages, we today would not have the faith. That is the foundation of our individual and collective gratitude for the working of God’s grace in their lives and thus of their cultus (in the way understood by the Church).
What Does It Means To Be Venerable?
The title “Venerable” states only that the Apostolic See has recognized the heroicity of the virtues of the Servant of God and has issued the relative decree. It does not authorize any public and ecclesiastical cult, which the Church usually concedes to Servants of God who have been canonized or only beatified.
Before the Code of Canon Law of 1917, the title “Venerable” was given to a Servant of God after the decree of the introduction of the cause. The Congregation of rites then prohibited the application of this title until the decree on the heroicity or martyrdom was issued (26 August 1913). This prohibition was confirmed in c. 2115, 2 of the Code of 1917.
