Christians don't care what the Bible says, they just pick and choose, or completely avoid mentioning what it says

Like this guy, a Jesuit Catholic priest, who fails to mention that the practice in Egypt was turbocharged by the Muslim conquest, and who should know better than to employ the is-is-ought fallacy:

This Easter, as some Christians get tattoos, this history might serve as a reminder of tattooing as a legitimate Christian practice, one that has been in use since the beginnings of the Common Era.

You must not slash your body for a dead person or incise a tattoo on yourself. I am the LORD. 

-- Leviticus 19:28

 

Catholic apologist for the faith Dave Armstrong tries to wriggle out of renunciation as the essence of discipleship

  Who Must Renounce All Possessions to Follow Jesus?:

To start with, it’s very important to consider to whom Jesus’ words apply in this instance. I deny that it is required of every Christian to leave their families, or to be single and celibate. That is the higher calling of what Catholics call the “evangelical counsels.” Some are called to that; most of us are not. St. Paul makes these distinctions very clear in 1 Corinthians 7.

I contend that what is being referred to in the passages above is the “above and beyond” discipleship of those who are apostles: a select group of individuals that were present and required only during the period of the very early Church. Not all disciples are apostles. In fact, 99.99% are not. The Bible repeatedly refers to the initial group of the disciples of Jesus, as “the twelve.”

Armstrong of course avoids Luke 14:33 altogether, which is part of the discourse addressed to the "great multitudes" beginning in vs. 25 (which includes "If any man come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple"):

So likewise, whosoever he be of you that forsaketh not all that he hath, he cannot be my disciple.

There is no idea of a "higher calling" here. The Twelve already exist, yet the "great multitudes" are called just as they were. There is only one standard of discipleship, and it applies to all equally, from high to low, from the rich young ruler to the lowly fisherman and every one in between.

Armstrong's other arguments tend to fall in the "is is ought" category of fallacy. Just because the disciples fell asleep in the Garden of Gethsemane despite Jesus' request that they watch and pray with him doesn't make it right! The disciples', not to mention Paul's, many instances of bad behavior making them bad disciples isn't proof that Jesus' retreated from his conceptions. How silly.

The guy argues like a proof-texter with nary a hint of subtlety.

Perhaps he was a former fundamentalist. The idea that certain things "were present and required only during the period of the very early Church" sounds like he had been a Baptist dispensationalist before he became a Catholic.

On a final note, apocalyptic eschatology, which is the sine qua non for understanding this and all of the New Testament, is, well, you guessed it, not in view.

Many Won't Be Fruitful And Multiply, But There's Only One Group Which Can't

"Do not be deceived."

"So God created man in his own image, in the image of God created he him; male and female created he them. And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth."

-- Genesis 1:27f.

"Be it then, as Sir Robert says, that anciently it was usual for men to sell and castrate their children, Observations, 155. Let it be, that they exposed them; add to it, if you please, for this is still greater power, that they begat them for their tables, to fat and eat them: if this proves a right to do so, we may, by the same argument, justify adultery, incest and sodomy, for there are examples of these too, both ancient and modern; sins, which I suppose have their principal aggravation from this, that they cross the main intention of nature, which willeth the increase of mankind, and the continuation of the species in the highest perfection, and the distinction of families, with the security of the marriage bed, as necessary thereunto."
