"18 Then Jesus approached and said to them, 'All power in heaven and on earth has been given to me. 19 Go, therefore, and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the holy Spirit, 20 teaching them to observe all that I have commanded you. And behold, I am with you always, until the end of the age'." (NABRE, Matt 28: 19-20)
"THE SACRAMENTS ARE EFFICACIOUS SIGNS OF GRACE, INSTITUDED BY CHRIST AND ENTRUSTED TO THE CHURCH, BY WHICH DIVINE LIFE IS DISPENSED TO US. THE VISIBLE RITES BY WHICH THE SACREMENTS ARE CELEBRATED SIGNIFY AND MAKE PRESENT THE GRACES PROPER TO EACH SACRAMENT. THEY BEAR FRUIT IN THOSE WHO RECEIVE THEM WITH THE REQUIRED DISPOSITIONS."
(Catechism of the Catholic Church ¶1131)
