Well, all I can say is that you called this thread “resources on Seventh-day Adventism” but there is only anti-adventism links posted for the “resources.”
You should have called it “How To Respond To Adventist” or “How To Debate With Adventists” That’s what adventistnomore should have called his thread too. It certainly is not a “witness” to point people to “apologetics” which are designed to tear down, rather than provide “resources.”
Some of Ratzlaf’s stuff which you laud and accolade is actually not in the true spirit of Catholic or Adventist thinking. Christians from many walks recognize this guy for what he really is; and it is very questionable to place a link to his article about the covenants, for eg., and call it an “adventist resource” or a “resource about Adventists.”
If you wanted info about what Adventists believe; you would be going more to Adventists to investigate, instead of to such negative debaters as we are seeing in links here.
The Covenants and The Law are not understood by Adventists, in quite the way such poison pen ministries would have you believe.
