[Natural Law]

"They don't want to stay members if it keeps changing in a left leaning manner and yet they can't bring themselves to actually leave as they know nothing but the Catholic Church."

Encourage them to get involved in their local parish or in a near by parish that better represents their beliefs and to work for the changes they desire. The laity, through their works, voices and prayers are the workmen of Christ and the instruments of change. Some within the Church have deviated because we allowed them to.

For me it begins with Catechesis. Every lapsed and former Catholic I know is the product of poor catechesis. Each of us has far more long term impact than we realize. Every wayward priest, bishop or Church official began their journey with the Catechism and at the feet of a volunteer. So did the saints and the pillars of our faith.

In his Catholicism series Fr. Barron recounts an exchange between Hans Kung and Henri de Lubac during Vatican II. As the two theologians were walking to a council session, Kung shared his frustrations with the institutional church. They approached the steps of St. Peter’s, de Lubac turned to Kung and said, “But she is still our mother.” Barron concludes: “We can’t treat her as ‘take it or leave it’…. No, the church is the place where we find the fullness of life, and that always has to be emphasized.”

Brother, these were hard core Catholics for years. They've been through all of that stuff.
They don't miss crossing themselves at any church or edifice even while driving and I've been with family when they actually drive around the block to drive back in front of one they didn't see in time! Oh their feeling of remorse. They couldn't stop talking about it.
Too wild! Imagine my confusion at nothing more than..."I've got to go back. I've just got to go back."
Most were heavily involved until about ten years ago or so. I don't know what happened back then, but that's about the time it started for them.

I'll still pass on your recommendations.
