Am I considered to be Catholic? I noticed with surprise the following in a previous question :


  Finally, each and every Catholic, as also the baptized of every non-Catholic church or denomination who enters into the fullness of the Catholic communion, 


I was baptised (in the name of the Father and of the Son and of the Holy Spirit) at the age of five (I can vividly remember it to this day, sixty-three years later) by a Presbyterian minister of the Church of Scotland.

At the age of fifteen I left the C of S and, for only a short time, joined with the Scottish Baptist movement and was baptised as an adult. 

I subsequently was dissatisfied with the state of religion in Scotland and I moved to England, at the age of eighteen, to be under the ministry and guidance of someone I perceived as a genuine Minister of Jesus Christ and I continued with him for twenty five years. He did not think it necessary to baptise me again and he accepted my baptism and received me into fellowship with his congregation.

I was married, now I am celibate. I no longer drink alcohol and I don't do drugs. I earn a living and I do not steal. I last told a lie (that I can remember) in 2011, of which I am ashamed, although it was not a matter of criminality. The last time I remember taking the name of God or the Lord in vain (as a curse or as an expletive) was when I was fourteen years old. 

So, am I accepted as Catholic or would I have to do anything further to be accepted as a Christian among Catholic persons ?
Are you considered to be Catholic?

The short answer is no.


  Finally, each and every Catholic, as also the baptized of every non-Catholic church or denomination who enters into the fullness of the Catholic communion, must retain his own rite wherever he is, must cherish it and observe it to the best of his ability, without prejudice to the right in special cases of persons, communities or areas, to have recourse to the Apostolic See, which, as the supreme judge of interchurch relations, will, acting itself or through other authorities, meet the needs of the occasion in an ecumenical spirit, by the issuance of opportune directives, decrees or rescripts. -  Orientalium Ecclesiarum


According to the above statement you have not entered into full communion with the Catholic Church. 

In order for that to happen several thing must happen first.

Validly baptized non-Catholics who desire to enter into full communion with the Catholic Church must complete an RCIA course which explains the basic beliefs professed in Catholicism, prior to making a profession of faith in the Catholic Church.


  The Rite of Christian Initiation of Adults (RCIA), or Ordo Initiationis Christianae Adultorum   (OICA) is a process developed by the Catholic Church for prospective converts to Catholicism who are above the age of infant baptism. Candidates are gradually introduced to aspects of Catholic beliefs and practices. The basic process applies to adults and older children, with younger children initiated through an adapted version sometimes incorrectly referred to as the Rite of Christian Initiation of Children (RCIC). - Rite of Christian Initiation of Adults
