Just a Sunday school teacher? No, not really.
Show us where Ted says he believes it is necessary for Christians to conquer earth before Christ can return.
Replace Ted with "Obama" and "conquer earth before Christ" etc. with "anti-American Liberation theology," and you'll understand the fallacious nature of denying that the sermons of Ted Cruz's own father, working as an agent of Cruz's campaign, along with Cruz's church culture, don't matter.
No, the Black Liberation Theology of Wright was taught from the pulpit. It was core to the teaching ministry of the church. That is profoundly different from having a controversial Sunday school teacher.
As for Rafael, you are not privy to the relationship going on there. Like I said, my own dad and I differed over the doctrines of grace. Had I been a political figure while he was alive, I am sure he would have supported me, and the theological differences we had would not have been a factor. You do not have evidence that Ted Cruz is anything but a typical Southern Baptist. No conviction for you. :)
Peace,
