Why the Holy Mass is SO Powerful

What are the purposes for which the Mass is offered?

  • First, to adore God as our Creator and Lord. 
  • Second, to thank God for His many favors.
  • Third, to ask God to bestow His blessings on all men. 
  • Fourth, to satisfy the justice of God for the sins committed against Him.
At the hour of death the Holy Masses you have heard devoutly will be your greatest consolation. 
By devoutly assisting at Holy Mass you render the greatest homage possible to the Sacred Humanity of Our Lord. ... 
Through the Holy Sacrifice, Our Lord Jesus Christ supplies for many of your negligences and omissions. 
He forgives you all the venial sins which you are determined to avoid. He forgives you all your unknown sins which you never confessed. The power of Satan over you is diminished. 
By piously hearing Holy Mass you afford the Souls in Purgatory the greatest possible relief.  
Through Holy Mass you are preserved from many dangers and misfortunes which would otherwise have befallen you. You shorten your Purgatory by every Mass. 
Through the Holy Mass you are blessed in your temporal goods and affairs.
When you hear Holy Mass devoutly, offering it to Almighty God in honor of any particular Saint or Angel, thanking God for the favors bestowed on him, etc., you afford that Saint or Angel a new degree of honor, joy and happiness, and draw his special love and protection on yourself.  
Every time you assist at Holy Mass, besides other intentions, you should offer it in honor of the Saint of the day. 
In holy Mass, in obedience to Christ's command, "Do this in remembrance of me," we of the Church offer perfect praise to the heavenly Father, and sanctify ourselves and the world by the power that flows from the priestly office of our eternal High Priest, Jesus Christ.  
The benefits of even one holy Mass are infinite and include the whole world. The blood of the new and everlasting covenant was "shed for you and for all."  
In every Mass that is offered the Church remembers before God "those who take part in this offering, those here present and all your people, and all who seek you with a sincere heart." In a special way those who have holy Mass offered and those for whom a Mass is offered partake of the grace of the Eucharistic sacrifice.  
The Church which offers Mass each day includes not only the faithful on earth, but the saints in heaven, as well as the suffering souls still awaiting entrance into heaven. 
It is a pious and praiseworthy custom for the faithful to have Masses offered for their particular intentions, and especially for departed friends and loved ones. It is a laudable Catholic practice when requesting Mass for a special intention to make an offering both for the support of the priest who will celebrate the Mass and to provide for the needs of the altar as well as the materials required for the holy Sacrifice.
It is very sad that so many non-Catholic Christians consider the Mass to be an abomination.  It is just the opposite.  It is the one-time sacrifice of Jesus on the Cross recreated, through time and space, in an unbloody fashion, just like Jesus did during the Last Supper.
