Actually, the formal conversion process can take multiple years in some cases, and well-implemented RCIA classes provide a comprehensive overview of exactly what new converts are getting into before the take that swim. In my class, each RCIA student was issued a Catechism for free. Not an abridged overview - the complete, official CCC. We spent four hours of class time in instructions on how to read it and how to find specific items within it, and the rest of our classes have mostly focused on detailed explanations of the sacraments, the liturgy and other important aspects of Catholic worship. I feel pretty confident that nowhere down the line will some weird “sacred” (translation: secret) doctrine or ritual be sprung on me.
That is not the Lord’s way nor the biblical way:
Acts 2:
37 Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?
38 Then Peter said unto them,
Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
39 For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.
40 And with many other words did he testify and exhort, saying, Save yourselves from this untoward generation.
41 Then
they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls.
Acts 8:
35 Then Philip opened his mouth, and began at the same scripture, and preached unto him Jesus.
36 And as they went on their way, they came unto a certain water: and the eunuch said, See, here is water; what doth hinder me to be baptized?
37 And Philip said,
If thou believest with all thine heart, thou mayest. And he answered and said,
I believe that Jesus Christ is the Son of God.
38 And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch;
and he baptized him.
That is the Lord’s way. No RCIA!
When we say that the early Christian church apostatized, and the doctrines, practices, and procedures were changed, these are the kinds of things that we have in mind. They are very good examples of that.
