You kneel down, close your eyes and stick out your tongue. The priest will place the Host on your tongue.
You should NOT be receiving Communion in the hand. This was an abuse that was later permitted by the Church when it should never have been. St Thomas Aquinas wrote:
Out of reverence towards this Sacrament, nothing touches it, but what is consecrated; hence the corporal and the chalice are consecrated, and likewise the priest’s hands, for touching this Sacrament. Hence, it is not lawful for anyone else to touch it except from necessity, for instance, if it were to fall upon the ground, or else in some other case of urgency” (Summa Theologiae, III, 82, 3).
Your hands are not consecrated like the priest’s, so you should not be touching the Sacrament.
According to BrJR. who has been a contributor to these forums, you are incorrect on a number of counts.
According to him, a number of centuries ago, the Franciscans applied to Rome and received permission to (again) receive in the hand, and that has continued up until Rome gave permission for Communion in the hand, subject to the local bishop’s approval.
In addition, reception in the hand goes back to documentation in the early Church, and continued for a number of centuries, until the Church granted wider permission. So, according to him, the matter was not done (starting in Europe) as an abuse; while the norm was reception on the tongue, reception in the hand not only was not specifically prohibited, but in fact was allowed in a very limited set (the Franciscans).
Quoting St Thomas has its penalties; and those are that if one does not know well the teachings of the Church, one can stumble onto parts of St. Thomas’s commentary which is contrary to Church teaching. St Thomas was a theologian, not a pope; and all theologians (him included, which he widely and openly acknowledged) speak of theological matters, but the Magisterium decides them. He was also wrong in some of his theological writings, for example, concerning doctrinal matters about Mary.
It may be your personal opinion that the Church should not have allowed, it, but your reasoning is wrong, and submission to the Church appears to be a matter of importance (per the Catholic Catechism of the Church).
And corporals are not consecrated. Not now, and not then. Furthermore, back when churches had altar rails, the cloth which was flipped over the rail at Communion time was not even cleaned (as a corporal is even now), but simply flipped back behind the rail.
