Thank you for your reply. The Error you describe falls under Indifferentism and False Ecumenism (that all beliefs are the same), “Every man is free to embrace and profess that religion which, guided by the light of reason, he shall consider true,” and “Man may, in the observance of any religion whatever, find the way of eternal salvation, and arrive at eternal salvation.” These are Errors number 15 and 16 condemned in the “Syllabus of Errors.”
All I am saying to everyone is to read the Encylicals and see what previous Popes have taught and how that corresponds (or doesn’t) to the teachings of the Church since VII. It isn’t difficult!
Some people prefer to believe that the Church began in 1969.
