If you want to become a Catholic, you must receive the Sacraments of Initiation. Baptism is the first. Once you are Baptized, Original Sin and all sins you've committed up until the Baptism are washed away. For all practical purposes, you will be a Catholic. However, your initiation is not yet complete. You must then receive the Sacrament of the Holy Eucharest; the Body and Blood of Christ in the appearance of bread and wine. From here, your next, and final step will be to receive the Sacrament of Confirmation. You will also want to consider receiving the Sacrament of Penance on, at least, an annual basis; certainly just prior to receiving one of the previously mentioned Sacraments.\n\nYou will want to check with your local Catholic parish, or maybe your Diocese. They will be able to give you the details for Catholic initiation.\n\nI find it strange that both your parents are/were Catholic but did not see to it that you already receive the sacraments of initiation. Depending on how much, or how little, formal religious education you may or may not have already received, you may need to study up on the faith so you are aware of the basics in time for receiving Sacraments.
