Welcome Martin,
Glad you have joined us. Dave from Tennesee mentioned "Christianity " apostasizing from the Truth and it's true. Consider that by the middle of the second century C.E. , according to a Gallop Poll, there was already 63 schisms or interpretations of what was considered " Christianity. "
Also consider the Scriptures of the New Testament from the First Century: Acts. 20:29,30. " I know that after my going away oppressive wolves will enter in among you and will not treat the flock with tenderness, and from among you yourselves men will rise and speak twisted things to draw away the disciples after themselves. "
1 John. 2:18,19. " Young children, it is the last hour, and, just as you have heard that antichrist is coming, EVEN NOW there have come to be MANY ANTICHRISTS from which fact we gain the knowledge that it is the last hour. They went out from us, but they were not of our sort, for if they had been of our sort, they would have remained with us, but they went out that it might be shown up that not all are of our sort. "
1 Timothy. 4:1-3 " However the inspired utterance says definitely that in later periods of time some will fall away from the faith, paying attention to misleading inspired utterances and TEACHINGS OF DEMONS, by the hypocrisy of men who speak lies, marked in their conscience as with a branding iron; forbidding to marry, commanding to abstain from foods which God created to be partaken of with thanksgiving by those who have faith and know the truth. "
As a suggestion, see and read: 2 Peter 2:1-3 ( false teachers among you); 1 Timothy 1:19,20( Hymenaus & Alexander); 2 Timothy 2:16-18 ( Their word will spread like GANGRENE); 2Thessalonians 2: 7-12 ( THEY MAY GET TO BELIEVING THE LIE).
These and many other Scriptures indicate that even in the First Century, especially towards the end of the century, near the death of the Apostle John, the LIE AND FALSE TEACHINGS GREW PROGRESSIVELY WORSE, SPREADING LIKE GANGRENE.
True Christianity WAS, HAS BEEN and IS in the minority from amongst professed " Christians "
Looking forward to your Posts and your comments in the days to come.
In Gods Love(Agapeo), Samson.
