"Thou shalt not bear false witness" a.k.a. 'one should not tell lies.' has been circumnavigated by the Catholic hierarchy right up to Pope John Paul II----especially in dealing with the sexual abuse scandals.  

This 'circumnavigation' was also taught in Catholic high schools to young girls who were in preparation to be secretaries in the 1950's and early 1960's.  Example:

Cardinal Ambrogio:  Sally.
Secretary Sally;  Yes, your Eminence?
Cardinal Ambrogio:  If Fr. Tridentinas calls and asks for me, tell him that I'm not in.  Always tell him that I'm not in.
Secretary Sally:  Yes, your Eminence.

Good Catholic secretary Sally, thinks to herself--- "Fr. Tridentias, the Cardinal is not in for YOU."

There has been doctrinal circumnavigation done for Centuries----whenever the official church wanted something:  phony documents showing that the Papal States belonged to the Pope, the Crusades, selling of Indulgences---and this little list doesn't pretend to be complete.
