Canada was founded as a Christian country.
God says in his Word,
Know, therefore that the Lord your God is God; he is the faithful God, keeping his covenant of love to a thousand generations of those who love him and keep his commands. But those who hate him he will repay to their face by destruction; he will not be slow to repay to their face those who hate him. Therefore, take care to follow the commands, decrees and laws I give you today.
Deuteronomy 7:10 (NIV)
There is too much at stake to allow ourselves to strip our great country of its Christian heritage.
