What are the prayers said at mass when entering?

When entering a Catholic Mass, congregants typically recite the Sign of the Cross, often followed by the Greeting from the priest, who may say, "The Lord be with you," to which the congregation responds, "And with your spirit." This is often followed by the Penitential Act, where the faithful acknowledge their sins and seek God's mercy, typically through prayers like the "Confiteor" ("I confess to Almighty God..."). These initial prayers set the tone for the worship and prepare the congregation for the liturgy.
