How to Convert to Catholicism?

That depends on whether you want to be a traditional or modern Catholic. Converts to the modern Catholic Church attend RCIA (Rite of Christian Initiation for Adults) classes & are then baptized into the Church at the Easter vigil. Traditional Catholics still follow the method used before Vatican II…converts study the catechism under the care of a tutor. After they have shown proficiency in the catechism, the priest will help them set a date for their baptism.
