Worship is an act of God in our lives.

Worship is prayer. We are called to worship God in all that we do and all that we are.  To always be in God’s presence by surrendering to Him. 

To worship God involves two things: God loving us and us responding to His love. First, God shows His love for us when He speaks, when He calls to us, and when He invites us into a life of His grace. Second, worship is us responding to God's incredible invitation by saying “yes”.  “Yes” to His love and “yes” to His will. Saying "yes" by surrending to Him - to a God who loves us more than we can even imagine.

Mass is the central act of worship of the Roman Catholic Church, which celebrates the Sacrament of the Eucharist. To worship God is to love God in the way we are called to love. To worship God means that He is indeed the God of our life and that nothing else is more important. It means allowing our heart, soul and mind to become immersed in God's love and filled with His presence. This is worship. And it's our calling in life.
 

"Sacraments are Signs of God's grace in our lives." USCCB

A Sacrament is a sacred and visible sign that is instituted by Jesus to give us grace, an undeserved gift from God. (See also CCC 1084).

Christ was present at the inception of all of the Sacraments, which He instituted 2,000 years ago. Christ is also present every time each Sacrament is celebrated. The Catholic Church has all of the seven Sacraments instituted by Christ, which include Baptism (cleansing of the soul), Confirmation (an outpouring of the Holy Spirit), Eucharist (or Communion), Anointing of the Sick, Holy Orders, Reconciliation (or confession of sins), and Matrimony. 

The Catechism of the Catholic Church explains that “the seven sacraments touch all the stages and all important moments of the Christian life.” (CCC 1210)

The whole liturgical life of the Church revolves around the Eucharistic sacrifice and the sacraments. (CCC 1113)

The Sacraments are efficacious signs of grace, instituted by Christ and entrusted to the Church, by which divine life is dispensed to us. The visible rites by which the Sacraments are celebrated signify and make present the graces proper to each Sacrament. They bear fruit in those who receive them with the required dispositions. (CCC 1131)
