talking to god confession
The pastor is the official witness of a sacramental marriage, with his permission, an assistant priest, or a deacon may witness it instead.
Yes, blessed ashes are a sacramental.
It's a question of custom. In the Catholic and some protestant churches like the Anglican Churches where the sacramental role of the priest is seen as important, then their clergy are called priests, as priests are given authority to perform sacraments - such as baptism and being the president at the Catholic mass or the Anglican Holy Communion. Of course, the priest is also seen as a teacher, preacher and has a pastoral role, but the sacramental role is seen as the priest's major emphasis. In most of the other protestant churches, the sacramental role of the clergy is not seen as so important, and therefore the 'priest' title is seldom used. Instead, the pastoral, teaching and preaching role is seen as more important and therefore their clergy are referred to as 'pastors' or 'ministers' (from the idea 'to minister to' - meaning 'to take care of') instead. They are still 'priests' in the sacramental sense, as they can still baptise and preside at communion services, but their emphasis is not seen as being here but in the role of pastor instead. So, neither name 'minister/pastor' or 'priest' is wrong - it is just a matter of custom and where the church places the emphasis on the clergy role.
Some Christian congregations have rules about marriage. If the marriage is done according to the rules of the religion, it is sacramental. All other marriages are non-sacramental.
no
Yes, a layperson can bless water in an emergency as a gesture of prayer and intention. It may offer comfort and support in challenging situations, though it does not have the same sacramental power as a blessing from a priest.
Deacons have pretty much the same authority as priests when it comes to blessing items and homes. A gift to the priest or deacon that makes a special effort to come out and do you a favor is always a good thing, but it is never required. Charging for sacraments or sacramental is known as simony and is a very bad thing. In other words, you may offer something to the priest, but you may not "pay" him.
be good
Yes
there is seven sacraments
The Pentitential Rite at the beginning of Mass is when we confess our sins and are absolved by the priest's blessing of venial (less serious) sins. Mortal (serious) sins must still be confessed in the sacrament of Penance (Confession).
