Can you please quote what you are talking about?
Seventh Session,
CANON XIII.-If any one saith, that the received and approved rites of the Catholic Church, wont to be used in the solemn administration of the sacraments, may be contemned, or without sin be omitted at pleasure by the ministers, or be changed, by every pastor of the churches whomsoever, into other new ones; let him be anathema.
The New Service was created against the will of the Church and thus against the will of Christ. It is therefore always illicit (not allowed) and those who knowingly attend it, share in the sin of its creators.
Other of its features are subjects of prior condemnation by the solemn Magisterium.
The Church forbids one to approach a doubtful sacrament under pain of sin.
Plus it is always a sacrilege and blashphemy against the Holy Mass of the Church and exposing yourself as a witness to these evil things harms your soul.
Couldn't the same be said of the Anglican service? And yet Canon Law in 1917 said Catholics could attend weddings and funerals just not actively participate. Did Canon Law contradict Divine Law?
I understand what you are saying. Anglican service is outside of the Church and it is dealt with by canon law because that is what canon law is, it is the law which regulates the actions and relations of men with one another and in relation to the Church.
The Novus Ordo on the other hand, takes place illicitly within the Church's sacramental system inside of the Church itself. It is on a completely different level than an Anglican or protestant service which does not claim to be the Catholic Mass of the Catholic Church.
The law gives you permission to be present at a non-Catholic service but not to worship at it but inside of the Church, the law never allowed for. or tolerated the presence of non-Catholic things.
The 1917 law does not give permission for the Anglican service to replace the Catholic Mass in the Catholic Church. Church law could never approve of such a thing so, even if it appears the same the issue is not at all interchangable one with the other.
