If you want to say that the prospects are bleak, you could say "it doesn't augur well." Augur is used as a verb in this English sentence, with no particular religious connotation. In ancient Rome, an augur was a religious figure who observed natural phenomena, like the presence and location to left or right of birds, to determine whether the prospects were good or bad for a proposed venture. If a bird were on the left, it would literally be sinister.

The morning star, which is also known as the planet Venus, was known as Lucifer, the light-bearer. Today Lucifer is thought of as Satan and not just a light-heralding morning star. English has acquired many words from Latin, or from Latin via French, and of these some had a religious significance in Ancient Rome or gained one in English. In the case of Lucifer, the religious significance was gained. A 'tenet' is something one holds as an element of one's belief system. In Latin, tenet simply means 'he holds.' Sometimes the religious words maintained their religious connotation: An omen is an 'omen'. A creator can still refer to the 'Creator'.
