The process of dating or courting someone for the sole purpose of converting them to Christianity.
Everyone knows Julia is just evangedating Andrew.
When a Christian falls in love with a heathen and they make up an excuse to date them anyways. They will "evangelicalize" to their significant other while they are dating, in hopes that they will understand the gospel.
Jane tried to evangedate Justin but he turned her down as soon as she made him go to church.
Sarah has been evangedating Drew for months, but I doubt he's ever gonna accept Jesus
