This is similar to the northern kingdom of Israel worshiping other gods after breaking away from Judah and Jerusalem following Solomon's death.
Sadly, I predict the same outcome for liberal mainline churches as experienced by ancient Israel - utter destruction.
Catholics worship God the Father, not God the Mother.
Oh! Wait!
You must be referring to our worship of Mary.
Which we don't do.
Try again.
I don't tell you what you believe -- please don't presume to tell me what I believe.
We were received into the Catholic Church after much prayerful study and conversation with various Anglican groups and Catholic parishes. Your idea that there is any "goddess worship" going on is unfounded and really borders on silliness.
I know a couple of REAL goddess worshippers (i.e. Wiccans, poor deluded souls) and the Blessed Mother is no doubt shocked at their goings-on. She rejects worship (although we give her great honor as God's mother) and in every way points us towards her Son. "Whatsoever he saith unto you, do it."
Good observations, If you are of the vine your church will prosper, if you are separated you will wither.
