The CCC is not Scripture.
This is all that's needed for salvation. While baptism is endorsed by Jesus in the verse you posted, He did not say that it was required for salvation. He says believing is.
John 5:24 Truly, truly, I say to you, whoever hears my word and believes him who sent me has eternal life. He does not come into judgment, but has passed from death to life.
In addition, the Holy Spirit tells us this....
John 1:11-13 He came to his own, and his own people did not receive him. But to all who did receive him, who believed in his name, he gave the right to become children of God, who were born, not of blood nor of the will of the flesh nor of the will of man, but of God.
Acts 16:27-31 When the jailer woke and saw that the prison doors were open, he drew his sword and was about to kill himself, supposing that the prisoners had escaped. But Paul cried with a loud voice, “Do not harm yourself, for we are all here.” And the jailer called for lights and rushed in, and trembling with fear he fell down before Paul and Silas. Then he brought them out and said, “Sirs, what must I do to be saved?” And they said, “Believe in the Lord Jesus, and you will be saved, you and your household.”
Romans 10:9-13 because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. For with the heart one believes and is justified, and with the mouth one confesses and is saved. For the Scripture says, “Everyone who believes in him will not be put to shame.” For there is no distinction between Jew and Greek; for the same Lord is Lord of all, bestowing his riches on all who call on him. For “everyone who calls on the name of the Lord will be saved.”
Amen!

Is repentance required? Confession with our mouths? Faith? Hearing the Word? Believing in our hearts? Calling on the Name of the Lord? Are these requirements or suggestions?
