The Church is no mere voluntary organization but a divine creation ordained by Christ for our salvation. To be members of the Church is to belong to the Body of Christ, Who is the invisible head of the Church. The Church has a visible head as well--the Pope of Rome, the successor to Saint Peter, upon whom Christ said that He would build His Church.
But Peter's office is not the only one that continues throughout history. The bishops of the Church are the successors of the other apostles, and they, together with the pope, teach and govern Christians for our sanctification and salvation.
The Church is the touchstone of our faith, the guarantor of orthodoxy. She is also the immediate source of the graces we need, through Her administration of the sacraments--but that's a lesson for another Sunday School.
Lesson Eleventh from the Confirmation Catechism has 8 questions. Note that the lesson begins with Question 114, continuing with the numbering from Lesson Tenth.
In the First Communion Catechism, the parallel lesson this week is Lesson Tenth. It includes 6 questions drawn from the Confirmation Catechism. The last two (Questions 128 and 133) are actually part of next week's lesson from the Confirmation Catechism, so you can skip them for now.
Check out this week's lesson, and if you have any questions, please leave them in the comments or ask them in the Catholicism Forum!
