Read Matthew 23, I believe quite of few of the Master's words were directed at large religious organizations like the Catholic church.
I believe that is YOUR fault, not the Catholic Church's. You must not have paid very close attention in CCD.
If you had no idea who Jesus was after going to church for 19 years, then all I can say is that you must have been mighty wilfully inattentive all that time. If you were so inattentive as to not listen to the Gospel being proclaimed nor acknowledge the offering of the Eucharist, then obviously you have no knowledge of the Catholic Church and are in no position to judge her. Furthermore, I don't believe an "altar call" is required by the Bible.
Sorry, Buddy, there always has been. Don't you remember the readings: the Gospels telling about Jesus' life, the letters of St. Paul -- usually the second reading -- instructing the communities that he was going out to in the beliefs of Christ, and the first reading, usually from the Old Testament, many of them prophecies about the coming of Jesus Christ????????
