Council of Trent (16^th century): Decree on Justification, Session VI, Chapter 4: "And this translation, since the promulgation of the Gospel, cannot be effected, without the laver of regeneration, or the desire thereof, as it is written; unless a man be born again of water and the Holy Ghost, he cannot enter into the Kingdom of God."

 Session VII, Concerning the Sacraments in General, Canon 4 (Denz 847): "If anyone shall say that the sacraments of the New Law are not necessary for salvation, but are superfluous, and that, although all are not necessary for every individual, without them or without the desire of them, through faith alone men obtain from God the grace of justification; let him be anathema."

No, you do not. You say that no sacrament is necessary, per St. Alphonsus, you are a heretic. 

"The heretics say that no sacrament is necessary, inasmuch as they hold that man is justified by faith alone, and that the sacraments only serve to excite and nourish this faith, which (as they say) can be equally excited and nourished by preaching.  But this is certainly false, and is condemned in the fifth, sixth, seventh, and eighth canons:  for as we know from the Scriptures, some of the sacraments are necessary (necessitate Medii) as a means without which salvation is impossible. Thus Baptism is necessary for all, Penance for them who have fallen into sin after Baptism, and the Eucharist is necessary for all at least in desire ( in voto)." - St. Alphonsus
