Bastards and church attendance

I am plowing through the Bible and have come across a right old statement. If you are a bastard none of your family for 10 following generations can enter a church. A generation is roughly 35 to 40 years therefore 350 to 400 years. The Lindsay clan was renowned for fornication in the 17th and 18th century. The family crest has bar sinister that is a diagonal black line this warns of bastards in the clan. The Lindsay clan has two bar sinister showing that there are a plethora of bastards in the family. So am I banned from entering a church? Looks like it.
