A billboard that declares only Christians can know God has blown up West Roxbury and Roslindale Facebook groups over the past couple of days, with posts from people saying we all need more Jesus in our lives alternating with posts with non-Christians and others who object to the in-your-face-message and posts from people who say everybody should just get over it.

The sign sits atop the Corrib Pub at Centre and Lagrange streets and replaces one that advertised the opening of the mini-Target in Roslindale.

The group that put up the sign, Christian Aid Ministries, spends several million dollars a year on billboards like this across the country. On one of its Web sites, the group explains why it opposes gay people, divorce in general and by women in particular, remarriage, masturbation by single people, abortion and the theory of evolution.
