This is a FINE example of what I mean by over-statement.
First there is a distinction between a statement made in error and a lie. It COULD be that the men you quoted were in error. But you immediately assert in a manner destined (I said "destined" not "intended")to create bad feeling, that they were liars. You do not seem to be painstakingly looking for the truth, but looking for a score in a debate.
Second, he is not alone in the assertion that there is Scriptural warrant for celebrating "the Lord's Day" rather than the pre-resurrection sabbath. But I'm sure as heck not going to discuss that on a thread which was allegedly NOT about whether the Trinity is a good Doctrine to hold but just what exactly the heck the doctrine is. (And, for the sake of completeness, I'm probably not going to debate it at all on Free Republic. Threads of this kind do not seem to contribute to charity or edification.)
This is a position contrary to the teachings and doctrinal holdings of the Catholic church. There is no scriptural warrant for any Sabbath other than the one God created in Genesis and spoke to the Hebrews in Exodus.
1Th 5:2 For you yourselves know full well that the day of the Lord will come just like a thief in the night.
Sunday has yet to catch me by surprise.
The trinity is also a doctrinal invention of the church at Rome. The Father and the Son are two seperate entities, if scripture is your guide.
Mat 7:21 "Not everyone who says to Me, 'Lord, Lord,' will enter the kingdom of heaven, but he who does the will of My Father who is in heaven will enter.
Mat 16:17 And Jesus said to him, "Blessed are you, Simon Barjona, because flesh and blood did not reveal this to you, but My Father who is in heaven.
Mat 26:53 "Or do you think that I cannot appeal to My Father, and He will at once put at My disposal more than twelve legions of angels?
I write boldly because I have confidence in my faith and the doctrines I hold. I understand that what I do here comes with great responsibility
Jam 3:1 Let not many of you become teachers, my brethren, knowing that as such we will incur a stricter judgment. Jam 3:2 For we all stumble in many ways. If anyone does not stumble in what he says, he is a perfect man, able to bridle the whole body as well.
I also readily admit that I do not have all the answers. If someone can show me irrefutable scripture that I should believe God is really some sort of Janus with 3 heads, then I will take the correction. If someone can show me the scripture relocates the Sabbath to the Day of the Sun, then I will take the correction.
Deu 4:19 "And beware not to lift up your eyes to heaven and see the sun and the moon and the stars, all the host of heaven, and be drawn away and worship them and serve them, those which the LORD your God has allotted to all the peoples under the whole heaven.
