Conversion is the turning or changing from sin to repentence, from a lax to a fervant way of life, from unbelief to faith, and from a non-Christian religion to Christianity. Those who enter the Catholic faith from a different Christian religion are said to enter into full communion with the Church. These DVDs explore the reasons many people go through these conversions and enter into full communion with the Church, even when it goes against what they have believed for their entire lives. They explain why the Catholic Church is the One True Church, and why, for many people, it's not a question of if they will become Catholic, but when.
