Yes, there are nominal "Christians" in all denominations. Wide is the gate that leads to destruction; narrow is the gate and few they be that find it.

He is a lying heretic, interpreting God's word to fit his own image. He is his own teaching Church. It is his interpretation of the Bible that is valid. He's living a holy life without sin, so he can cast the stones. Typical hypocritical heretic.

Luke 18:9-14 “To some who were confident of their own righteousness and looked down on everybody else, Jesus told this parable: ‘Two men went up to the temple to pray, one a Pharisee and the other a tax collector. The Pharisee stood up and prayed about himself: “God, I thank you that I am not like other men – robbers, evildoers, adulterers – or even like this tax collector. I fast twice a week and give a tenth of all I get.” But the tax collector stood at a distance. He would not even look up to heaven, but beat his breast and said, “God, have mercy on me, a sinner.” ‘I tell you that this man, rather than the other, went home justified before God. For everyone who exalts himself will be humbled, and he who humbles himself will be exalted.’”

I don't know any Protestants. People are either saved and are true followers of Christ or they are not. There are no denominations mentioned in the Bible; you either worship God in Spirit and Truth or you fall short.
