Americanism

Americanism has been addressed by Holy Mother Church, and Pope Leo XIII had dedicated an entire encyclical to dealing with problems associated with this error.

Here is an excerpt:

The underlying principle of these new opinions is that, in order to more easily attract those who differ from her, the Church should shape her teachings more in accord with the spirit of the age and relax some of her ancient severity and make some concessions to new opinions. Many think that these concessions should be made not only in regard to ways of living, but even in regard to doctrines which belong to the deposit of the faith. They contend that it would be opportune, in order to gain those who differ from us, to omit certain points of her teaching which are of lesser importance, and to tone down the meaning which the Church has always attached to them. It does not need many words, beloved son, to prove the falsity of these ideas if the nature and origin of the doctrine which the Church proposes are recalled to mind. The Vatican Council says concerning this point: "For the doctrine of faith which God has revealed has not been proposed, like a philosophical invention to be perfected by human ingenuity, but has been delivered as a divine deposit to the Spouse of Christ to be faithfully kept and infallibly declared. Hence that meaning of the sacred dogmas is perpetually to be retained which our Holy Mother, the Church, has once declared, nor is that meaning ever to be departed from under the pretense or pretext of a deeper comprehension of them." -Constitutio de Fide Catholica, Chapter iv. (Testem Benevolentiae Nostrae) 

It is truly imperative that Catholic do not get washed away with the waves of dissident rhetoric which pervade society, but instead follow the sacred truths of the Church. Not an inch of way should be given to those who corrupt the faith without putting up a fight.

We are called to love our God with all our whole heart, whole soul, with all our strength, and with all our mind. Additionally, we must love our neighbor as ourselves. This means that we should never abondon the fight and become indifferent to the salvation of souls. This is a fight that concerns all of us. We cannot sit back as spectators; we all have an active role to play. This battle is not optional, but is required of all Catholics, who are the Church Militant.

Let us be ever vigilant and work to honor and love our God in all that we do. This also means that we should not be afraid to share the gospel, if not by actual word, then by deed, as the way we lead our lives reflects upon the faith we hold dear. In our daily pursuits, we must be ready to voice our opposition in all walks of life against that which goes against the eternal truth, especially that which corrupts the Church from inside.
