1Ki 12:26 Jeroboam said in his heart, "Now the kingdom will return to the house of David.
1Ki 12:27 "If this people go up to offer sacrifices in the house of the LORD at Jerusalem, then the heart of this people will return to their lord, even to Rehoboam king of Judah; and they will kill me and return to Rehoboam king of Judah."
1Ki 12:28 So the king consulted, and made two golden calves, and he said to them, "It is too much for you to go up to Jerusalem; behold your gods, O Israel, that brought you up from the land of Egypt."
1Ki 12:29 He set one in Bethel, and the other he put in Dan.
1Ki 12:30 Now this thing became a sin, for the people went to worship before the one as far as Dan.
1Ki 12:31 And he made houses on high places, and made priests from among all the people who were not of the sons of Levi.
1Ki 12:32 Jeroboam instituted a feast in the eighth month on the fifteenth day of the month, like the feast which is in Judah, and he went up to the altar; thus he did in Bethel, sacrificing to the calves which he had made. And he stationed in Bethel the priests of the high places which he had made.
1Ki 12:33 Then he went up to the altar which he had made in Bethel on the fifteenth day in the eighth month, even in the month which he had devised in his own heart; and he instituted a feast for the sons of Israel and went up to the altar to burn incense.

Thank you for posting that scripture. It reminds me also of when Aaron created his own holy day:

Exo 32:4 And he received them at their hand, and fashioned it with a graving tool, after he had made it a molten calf: and they said, These be thy gods, O Israel, which brought thee up out of the land of Egypt.
Exo 32:5 And when Aaron saw it, he built an altar before it; and Aaron made proclamation, and said, Tomorrow is a feast to the LORD.

In both cases, they thought, they believed, that they were creating holy days that were acceptable to the one true God. So what if they added a couple of pagan elements? After all, they were worshiping the LORD. But of course we know that both times it turned out pretty ugly.
