<p>As a non-Catholic, you should not participate in communion. There are exceptions for Eastern Orthodox, but generally speaking communion is limited to Catholics. Catholics believe in the doctrine of transubstantiation, meaning that Christ is physically present in the Eucharist. The idea is that only people who share that belief should participate in communion. Protestants rarely share that belief. </p>
<p>Usually, First Communion takes place at a regular mass. That means you will be sitting through an entire mass. You should expect that the mass will take at least an hour.For First Communion, it will probably be closer to an hour and a half. </p>
<p>At some point, a collection will be taken up. You should not feel obligated to contribute. At some masses, there is also a second collection for some special event. Again, don’t feel oblgated to contribute. I’m just letting you know it will happen, so you won’t feel disconcerted when it happens.</p>
<p>You don’t say what faith you are, but if you have ever attended a Lutheran mass, it’s very, very similar. There are 3 readings. You will be expected to stand for the third one, which is the Gospel. </p>
<p>There is a lot of sitting, standing, kneeling in a mass. Just follow what the others do. </p>
<p>There are usually “missalettes” in the pew which have the readings for the month in them, so you can folllow along if you wish. I think you will find some of the prayers familiar and you are free to join in–or not. </p>
<p>I don’t think you are obligated to give a gift at all. A nice card would be fine. If you want to do so, fine. While traditionally gifts for those making First Communion are religious, it’s not horrible to give anythiing appropriate for a child of the age. Your friend knows that you aren’t Catholic. </p>
<p>For First Communion for a pricey gift, a simple gold or silver cross necklace is a lovely gift for a girl. You can probably find a Catholic book store in your area and find a “life of the Saints” type book if you want to do this. You might consider getting a gift card at such a store too. </p>
<p>But really, anything is fine. I don’t like giving cash to people I don’t know well, but that may just be me.</p>
